Research by scientists at King’s College London found that the role the gut plays in processing and distributing fat could pave the way for the development of personalized treatments for obesity and other chronic diseases within the next decade. The research is published in Nature Genetics.
In the largest study of its kind, scientists analyzed the faecal metabolome (the community of chemicals produced by gut microbes in the faeces) of 500 pairs of twins to build up a picture of how the gut governs these processes and distributes fat. The King’s team also assessed how much of that activity is genetic and how much is determined by environmental factors.
The analysis of stool samples identified biomarkers for the build-up of internal fat around the waist. It’s well known that this visceral fat is strongly associated with the development of conditions including type 2 diabetes, heart disease and obesity.
By understanding how microbial chemicals lead to the development of fat around the waist in some, but not all the twins, the King’s team hopes to also advance the understanding of the very similar mechanisms that drive the development of obesity.
An analysis of faecal metabolites (chemical molecules in stool produced by microbes) found that less than a fifth (17.9 per cent) of gut processes could be attributed to hereditary factors, but 67.7 per cent of gut activity was found to be influenced by environmental factors, mainly a person’s regular diet.
This means that important changes can be made to the way an individual’s gut processes and distributes fat by altering both their diet and microbial interactions in their gut.
On the back of the study researchers have built a gut metabolome bank that can help other scientists engineer bespoke and ideal gut environments that efficiently process and distribute fat. The study has also generated the first comprehensive database of which microbes are associated with which chemical metabolites in the gut. This can help other scientists to understand how bacteria in the gut affect human health.
Lead investigator Dr. Cristina Menni from King’s College London said: ‘This study has really accelerated our understanding of the interplay between what we eat, the way it is processed in the gut and the development of fat in the body, but also immunity and inflammation. By analysing the faecal metabolome, we have been able to get a snapshot of both the health of the body and the complex processes taking place in the gut.’
Head of the King’s College London’s Twin Research Group Professor Tim Spector said: ‘This exciting work in our twins shows the importance to our health and weight of the thousands of chemicals that gut microbes produce in response to food. Knowing that they are largely controlled by what we eat rather than our genes is great news, and opens up many ways to use food as medicine. In the future these chemicals could even be used in smart toilets or as smart toilet paper.’
Dr. Jonas Zierer, first author of the study added: ‘This new knowledge means we can alter the gut environment and confront the challenge of obesity from a new angle that is related to modifiable factors such as diet and the microbes in the gut. This is exciting, because unlike our genes and our innate risk to develop fat around the belly, the gut microbes can be modified with probiotics, with drugs or with high fibre diets.’
Retiring from the armed forces can be a very stressful transition because there is no magic crystal ball that allows you to see into your future as a civilian. Veterans often have strong networks built over the course of their military service, but as useful as these networks are, they are also apt to keep you from branching out into something new, or taking time off to pursue uncharted possibilities. You don’t know what you don’t know, so it is easy to fall into a trap where income becomes the driving force behind career decisions rather than a deep introspective look into what you really want out of life. This leads to a pursuit of employment rather than fulfillment, and ends in a contract that forces you to trade more of your precious time for money. After giving so much to your country, and asking your family to sacrifice just as much or more, taking time to reconnect with them and yourself before a second career is worth your consideration. You might be pleasantly surprised where it will lead.
Consider the following in your calculus:
Military service didn’t leave much room for hobbies and passions. Do you have any languishing in the recesses of your life?
Military regulations and culture compelled you to identify yourself by an all-consuming job title, which in turn suppressed your identity as an individual. You were the Admiral, the Colonel, Skipper, Warrant, Chief, Senior, Top, OPSO, COS, the LPO, the First Sergeant. Do you really know who you are anymore without a job title to define you?
Time keeps ticking, but money comes and goes. Is time more valuable than money when you realize that you can bank one but not the other?
This last thought is the one that gave me the most pause. If you are shackled to a life dictated by consumerism and workism, your “one day” list becomes less and less achievable. This is paradoxical, because chances are you might be making a decent salary on top of your retirement income, but you don’t have time for you, your spouse, your kids, your dog, your forgotten hobbies, or your wild and crazy ambitions. Why? Because your new job might provide a comfortable existence and a title to impress your friends, but it doesn’t guarantee you will have time for anything on your bucket list. How many successful people have all the toys in the world but no time to use them? More than you think. In this article, I will argue that as a veteran, you have been given all the resources you need to thrive in a life of your choosing. To be clear, I am not suggesting that you become completely “checked out” and retreat from society never to work again. Instead, I am advocating for a period of time that prevents you from rushing headlong into a second career. This will give you some “maneuver space” to sort through the stress, the noise, and the pressure that is screaming at you to immediately get a job and keep slogging forward. That space might be a few months, or it might be a few years, but either way, it is time well-spent.
Try this little exercise. Mentally fast forward to the end of your life. You are looking back on your experiences wondering why you worked your whole life, yet missed out on so much living. Maybe you wanted to take a year and surf the south Pacific, or fish the great rivers in Alaska, or hike the Appalachian Trail, or follow the Tour de France, or start a business, or write a novel, or raise alpacas, or sell it all and buy a sailboat…but you didn’t, and now you are too old and tired to do anything but look back with sadness and regret. You realize there was always something standing in the way; there were always reasons why you couldn’t. So, instead of doing, you resigned yourself to watching others as you scrolled through your social media feeds and groused about your boss, staff meetings, the person who chews their food too loudly in their cubicle, the jerk who cut you off on your commute, and the endless mundane aspects of life in “The Matrix.”
As you contemplate those lost dreams, you might be asking yourself with a twinge of frustration, “Why didn’t I go for it? What was I afraid of? What was the worst thing that could have happened to me if I had unshackled myself from the ‘golden handcuffs,’ put down the electronic tether, and lived the life I always imagined?” You might be surprised to learn the worst thing that could have happened was nothing from which you could not have quickly recovered.
Now, rewind to the present. Ask yourself this question, “Have I ever allowed myself to fail?” If you made it all the way through a 20-year (or more) career, chances are the answer is a resounding no! So why do you think you will start failing now? I’ll let you in on a little secret…you won’t. You already know how to succeed. The sad truth, however, is that many of us never take a chance, because we focus on the reasons we shouldn’t…the fears…rather than the reasons we should…the inspiration.
Every military member goes through transition class on their way out of the service. You learn that it is possible to reinvent yourself, but it isn’t easy. You are instructed to make a list of your assets, your liabilities, and any gaps you have in your skill set, then cross-reference it against what you need to break into a sector outside of what you have been doing for the past twenty-plus years. You are told to be willing to move to an area where that sector has a presence, be patient, be willing to evangelize yourself, build a network in your new community, use your hard-earned benefits to get the education or certifications you need to fill in any gaps, and be willing to start at the bottom. If you do these things while exhibiting all the qualities that made you successful on active duty, you will succeed.
What if I told you that same blueprint for reinventing yourself professionally is just as useful for reinventing yourself personally, and going after those “one day” dreams before you blindly (or deliberately) trade one overlord for another. With a little bit of planning and foresight, you can do it, and if I haven’t made my position clear, I think you should. When else will you get a planned break in your professional life to do something crazy?
I started my transition playing by the rules. I spent hours…no, weeks…working on a resume. I went to career fairs. I interviewed for jobs. I received job offers. None of it felt right in my gut. I started terminal leave in June 2018 in a panic-stricken state, grasping for a lifeline. At my wife’s urging I had been exploring the idea of trade school using my GI Bill benefits, but I was afraid to commit. “It’s not what I am expected to do,” was my typical reason, which was ridiculous. I was afraid of the unknown and everything that came with it. That was the truth. I had reached the first portal of fear, and with my wife’s encouragement, I stepped through it.
Once again, I found myself grasping for the familiar and hiding from my fears. I applied for a government job overseas, knowing it wasn’t what I really wanted. A friend was recruiting me to come back to the staff I had left a year and a half earlier, but after I submitted my resume, there were knots in my stomach. “What am I doing,” I asked myself. “Is this what I really want?” I wasn’t ready for staff meetings and point papers again. I wasn’t ready for days when I went to work at dawn and came home after dinner just to get up and do it all over again while my life ticked away a second at a time.
My wife had a dream that we could sell it all and go sailing. I was adamantly opposed. “If there is one thing I learned at the marine trade and technology school,” I joked, “it is don’t buy a boat!” The truth of the matter is I was terrified of selling everything and buying a boat. There were too many voices in my head telling me it would be our ruination…MY ruination. I hid behind my biggest fear – money. We couldn’t afford it. End of story.
But, it wasn’t.
It’s amazing what you can accomplish when you put your mind to it. As I tell my children, there is a solution to every problem, we only need to outthink it. So we looked at the problem again and realized we could afford it. But, I still wasn’t ready to commit. I needed a push.
Fate intervened on my behalf. Much to my surprise, my resume never made it through the initial screening for the civil servant position, so I never got the job interview on the staff overseas. Despite my ego being bruised, I actually breathed a sigh of relief. I was a free man again. A few weeks later, after some long, introspective conversations with my wife, I agreed to the sailing adventure. Failure had somehow opened a pathway to an outcome I did not think possible. That was in March 2019. Four months later, we would be boat owners after an exhausting push to sell, donate, or repurpose just about everything we owned. Three months after that, we would be getting underway from Hampton, VA for a 1,600 nautical mile ocean passage to Antigua.
How did we go from “normal life” to “boat life” so quickly? We followed the same blueprint I received in the transition seminar. We laid out a plan, prioritized our resources, and focused everything we had on the achievement of our goal. I had already filled in the knowledge gaps by becoming a certified marine mechanic. Anyone who knows boats will tell you that 90% of boat ownership is boat maintenance, so I felt confident I could handle that responsibility with my new skills. I grew up sailing, so that wasn’t an issue, but living aboard a boat full-time was another story. We hired a couple who had twice circumnavigated with their kids as “cruising coaches.” We built a network by talking about our plans with people who could help and guide us. We made sure we were able to fund our dream by paying cash for a boat and living within the means of my retirement income. Using our new and growing network, we found a boat, brokered the deal, and moved aboard on July 31, 2019.
It was not an easy transition from land life to sea life. In fact, it was harder than anything we had ever done. Being a military family, we were used to relocating and starting over every couple years, so we put all that experience to good use. But, this time it was different. It was all on us to get it done. There were at least three distinct points when we wanted to quit. We didn’t, largely due to the encouragement and instruction we received from people who had walked the same path. The rewards for persevering are too many to list. Suffice it to say, I answer to no master. I have learned more about myself and my family in six months than I have in six years. I have swum with a whale in 19,000 feet of water halfway between Bermuda and the Leeward Islands. We have sailed our way through 50-knot squalls and come out the other side stronger and more resilient. I have made lifelong friendships with people I would never have met had I stayed in my “safe” bubble. I have gained valuable perspective by using this time away from the rat race to sort myself; to be a better husband, father, and friend.
A good counterargument to this conversation would go something like this – “My professional stock is highest immediately after I retire. It will be irresponsible for me not to take advantage of that transition point and start building my professional resume in the real world. Statistics support the fact that I most likely will change jobs several times as I find my niche, so it doesn’t matter what I do. The important thing is to get into the ring and make a name for myself.” So you get a job and a fancy-sounding title that you eagerly post on LinkedIn. You beef up your profile with a power photo that has you leaning into the camera with a smile that says, “I’m a go-getter!” You add a description underneath that says something like, “I’m a results-oriented leader with a proven track record of astonishing accomplishments, fiscal maturity, operational prowess, cunning initiative, etc, etc, etc.” It becomes your identity, and it is the right thing to do, isn’t it? I certainly thought it was. But for me, at least, it wasn’t. I am not getting any younger. Neither are you. The counterargument doesn’t hold up, in my opinion. You can always get a job and make money, but you can’t make more time. Another aspect of this counterargument is that your network will abandon you if you take time for yourself and your family. I also believe that this is invalid, and would go so far as to suggest that your network will respect you more for leading in this manner.
We as Americans have it all backwards. We work and work and work until we hit the “golden years,” then we retire with the idea that we are going to take off from our empty nest and explore the world. I have heard so many tragic stories about people who FINALLY get some time to do the things they have always wanted to do only to be sidelined by unexpected health crises that leave them debilitated or worse. Derek Thompson, a senior staff writer for The Atlantic wrote a compelling article in February 2019 titled, “Workism is Making Americans Miserable,” where he argues that work has become, unfortunately, the, “centerpiece of one’s identity and purpose.” It’s an excellent, thought-provoking read.
Work, pay taxes, then die.
As a retiring military member, you have the resources to do what you want – healthcare, education opportunities, steady income, and many more benefits to jumpstart your second life. You only need to face down your fears and embrace the possibilities that lay before you. I am not done working, but I guarantee whatever employment I pursue in the future will be far different than what I thought I had to shoehorn myself into when I first transitioned from service. We have had a lot of people tell us how amazing our life is…how lucky we are…how courageous we are to be out sailing with our kids full time. We don’t see ourselves as different or special. We are just us, living a life of our choosing. We realized in hindsight that fear had been holding us back, not resources. Once we made our decision, we were flabbergasted by how everything suddenly seemed to align behind us. It was all there to begin with, but we were blinded by our fears of the unknown, and therefore too afraid to take a chance.
Fear is paralyzing, and in the weeks surrounding my transition there were days when I didn’t want to get out of bed and face reality. In the middle of those dark moments, a very wise friend of mine asked me to stretch my hands out in front of myself palms up, then she had me clench my fists. She looked at me and said, “There won’t be room for anything new in your life if you are holding onto everything so tightly, afraid to let go. You have to open your hands and be willing to release – toxic relationships, needless possessions, clutter, the wrong career, convenience, the safe and easy path, money. But more importantly, you have to open your hands so what you really want has a place to land.”
I stood there for a moment clenching and unclenching my upturned hands. I am not a particularly spiritual person, but I was shocked at how profoundly her simple exercise struck a chord. “Money comes and money goes, and it should,” she concluded, “but even though we have had our backs to the wall a number of times, we always believed we would be fine because we kept our hands, figuratively of course, upturned and open.” She and her husband are better now than ever after launching their own business nearly twenty years ago. They had been let go from their previous jobs at the same time, when their kids were still young, and their stress levels already high. In that moment of darkness, they chose to open their own business and live life according to their own terms. It wasn’t easy, but looking back, they wouldn’t want it any other way.
In the final analysis, it’s not about how much you have, but what you do with it. Achieving your ambitions means making decisions, prioritizing and leveraging resources, and aligning efforts. Do you want to be linked in right away, or checked out to gain some perspective and clarity? The choice is yours, and it doesn’t matter how big your proverbial or actual boat is. It only matters that you believe in yourself and face down your fears. Trust me, someone always has a bigger boat. You can find dozens of YouTube channels where people are sailing the world on every manner of boat imaginable. I used to watch some of them and say, “Look at their boat. It’s so ugly, or small, or dilapidated.” My wife would answer, “Yeah, sure is…but they are doing it!” How true. Would you rather be sitting in a staff meeting wishing you were doing it, or actually doing it?
I’ll close with this final thought. Many, if not all of us, who are retiring from a career in the service lost shipmates, close friends, and comrades in training and combat. A few years ago, standing on a beach in Italy looking out into the Adriatic Sea, where a friend in Air Wing 17 had perished during a nighttime training flight off the USS George Washington (CVN-73) in 2002, I made a promise that if I somehow made it through my military career, I would not squander the opportunity to fulfill dreams and live an amazing life. I felt like I owed that to those who couldn’t. Life is short, and precious. Don’t let fear hold you back. Don’t let a false sense of obligation keep you from doing the things on your “one day” list. If you do, that list will go unfulfilled.
We keep a sign on our boat that reads, “Everything you want is on the other side of fear.” It is a constant reminder for us to keep pushing forward. You can, too.
Glenn Robbins is a retired Naval Officer cruising full-time on a 46-foot catamaran named FEARLESS with his wife Andi and their two children, Gavin and Alexis.
A Chinese warship threatened a US Navy destroyer during a tense showdown in the South China Sea in late September 2018, according to new details of the encounter.
A Chinese People’s Liberation Army Navy Type 052C Luyang II-class destroyer challenged the US Navy Arleigh Burke-class guided-missile destroyer USS Decatur during a routine freedom-of-navigation operation near the disputed Spratly Islands. The Chinese warship sailed within 45 yards of the American vessel, nearly colliding with the US destroyer.
The Chinese vessel “approached USS Decatur in an unsafe and unprofessional maneuver in the vicinity of Gaven Reef in the South China Sea,” where it engaged in “a series of increasingly aggressive maneuvers accompanied by warnings for Decatur to depart,” a spokesman for the US Pacific Fleet said in a statement. The Decatur was forced to change course to avoid a collision.
A transcript of the radio exchange between the two naval vessels obtained by the South China Morning Post from the British Ministry of Defense shows that the Chinese ship threatened the Decatur, warning that it would “suffer consequences” if it did not move.
“You are on [a] dangerous course,” the Chinese destroyer warned over the radio. “If you don’t change course, [you] will suffer consequences.”
“We are conducting innocent passage,” the Decatur reportedly replied.
In a video of the incident, an unidentified Navy sailor can be heard saying that the Chinese ship is “trying to push us out of the way.”
The video is a little unclear, but there appear to be ship fenders deployed off deck, Collin Koh, a research fellow at the S. Rajaratnam School of International Studies, noted on Twitter. He explained that “fenders are designed to mitigate the kinetic impact of a collision,” adding that the deployment is “clearly an indication of preparedness for such an eventuality.”
Ankit Panda, a foreign-policy expert who is a senior editor at The Diplomat, called the incident “the PLAN’s most direct and dangerous attempt to interfere with lawful US Navy navigation in the South China Sea to date.”
Unsafe or unprofessional encounters between the US Navy and the Chinese military are, however, not particularly uncommon. “We have found records of 19 unsafe and/or unprofessional interactions with China and Russia since 2016 (18 with China and one with Russia),” Cmdr. Nate Christensen, a spokesman for the US Pacific Fleet, recently told CNN.
A number of these incidents involved dangerous Chinese intercepts of US Navy aircraft. In August 2018, the Chinese military sent a total of six warnings to a US Navy P-8A Poseidon reconnaissance plane, warning it to “leave immediately and keep out.”
It is potentially noteworthy that the details of the showdown between the US and Chinese warships in the South China Sea came from the British Ministry of Defense, as a British naval vessel also found itself in a standoff with the Chinese military in the South China Sea not too long ago.
In early September 2018, China dispatched a frigate to to take on the UK Royal Navy amphibious assault ship HMS Albion when it sailed too close to Chinese outposts in the Paracel Islands. China called the incident a provocation and warned that it would “take all necessary measures to defend its sovereignty and security.”
The US Navy is apparently expecting incidents like this to occur more frequently going foward. The US and China “will meet each other more and more on the high seas,” Chief of US Naval Operations Adm. John Richardson said Oct. 30, 2018.

The Corps’ deputy commandant for aviation, Lt. Gen. Jon “Dog” Davis, said Wednesday at the Unmanned Systems Defense conference in Arlington, Virginia, that this future platform — a Group 5, the largest class of military drone — will be equipped to fight from sea as well as land.
“I would say we’re very aggressive with what we want that Group 5 to be,” Davis said. “I want my airplane to go off a seabase and, frankly, I think the Group 5 [unmanned aircraft system] for the Marine Corps will have [AIM-120 Advanced Medium-Range Air-to-Air Missile] on there, will have AIM-9X [Sidewinder missile], will have all the weapons that an F-35 will carry, maybe even the sensors the F-35 will carry.”
This future drone will not be a competitor with the Corps’ new F-35B Lightning II 5th-generation fighter but a collaborator, able to team with the aircraft on missions, he said.
“It’s about … making sure that the Marines have the very best protection wherever they go, whatever they do, and manned-unmanned teaming is not just with attack helicopters — it’s with jets, it’s with grunts,” Davis said.
In the Corps’ 2016 aviation plan, the MUX is described as filling an extremely broad range of missions, including electronic warfare; reconnaissance and surveillance; command, control, communications and computers [C4]; aircraft escort; persistent fires; early warning; and tactical distribution.
“It will be a multi-sensor, electronic warfare, C4 bridge, [anti-air warfare] and strike capability at ranges complementary to MV-22 and F-35, giving MAGTF commanders flexible, persistent, and lethal reach,” the document states. “It will provide scalable MAGTF support deploying as detachments or squadrons supporting commanders at the tactical, operational, and strategic levels.”
Call it a mega-drone, if you will.
Prominent candidates for such a role include the Bell-Textron V-247, an unmanned, single-engine armed tiltrotor platform designed to operate from the sea; the Lockheed Martin K-Max built by Kaman, an optionally manned cargo chopper used to transport gear in Afghanistan and now being developed to accommodate sensors; and the Tactically Exploited Reconnaissance Node, or Tern, an aircraft developed by DARPA and the Office of Naval Research that sits on its tail so it can launch and recover on a ship’s deck.
Davis said he wants the Marines’ Group 5 UAS to be able to fly at 30,000 feet, the typical cruising altitude for an airliner, and to carry weapons internally to maximize efficiency and time on station. Ultimately, he said, he wants an unmanned aircraft that can do everything a manned aircraft can.
“Do I think it will replace manned platforms? No, but I think we have to integrate, look for capabilities, cover down our gaps, our seams, that are out there,” he said. “Frankly, no matter how many airplanes I have, I don’t get 24/7 coverage with my manned platforms, especially from my seabase. If we do distributed operations, we’re going to need all the game we can bring.”
Davis said he wants to see a tech demonstration flight of the MUX by 2018 and early operational capability for the system by 2024.
That timeline puts development of the mega-drone slightly ahead of the joint Future Vertical Lift program, which will select a next generation of helicopters for services including the Army and Marine Corps.
Conflicting reports from U.S. officials and terrorist leaders suggest a top commander of the militant Islamic State group might have been killed in a U.S. airstrike near the embattled Syrian town of Aleppo.
The Pentagon said in a release late yesterday that a precision airstrike had targeted a vehicle that officials say Abu Muhammad al-Adnani was riding in. Al-Adnani was believed to be the ISIS group’s top spokesman and a key player in inspiring so-called “lone wolf” attacks on Western targets, including the shooting rampages in Paris, France, and Orlando, Florida.
“Al-Adnani has served as principal architect of ISIL’s external operations and as ISIL’s chief spokesman,” Pentagon spokesman Peter Cook said in a statement. “He has coordinated the movement of ISIL fighters, directly encouraged lone-wolf attacks on civilians and members of the military and actively recruited new ISIL members.”
While the American military was uncertain whether Al-Adnani had been killed in the strike on Al Bab, near Aleppo, the Islamic State confirmed his death in a statement.
Analysts say the result, if confirmed, is an effective blow against the terrorist group, which has seen its hold on territory in both Iraq and Syria wither under U.S., coalition and Russian air and ground assaults in recent weeks.
“He was an important Islamic State leader and one of the top remaining leaders of the old guard,” said terrorism analyst and founder of The Long War Journal Bill Roggio. “It’s definitely a good kill.”
But while ISIS has now lost three of its top leaders in one year, the death of al-Adnani could have the unintended consequence of bringing rival terrorist groups together. For years, Roggio says, al-Adnani has been at odds with al Qaeda — eventually causing a very public split and disavowal from Osama bin Laden’s successor, Aymen al Zawahiri.
With al-Adnani gone and only one of the Islamic State’s founding leaders left on the battlefield, the group behind the 9/11 attacks could rise as ISIS falls.
“In it’s way, al-Adnani’s death could pave the way for a rapprochement with al Qaeda,” Roggio said. “It could have implications that could bolster other jihadist movements.”
Al-Adnani may have been an important leader and a key victory in the war against ISIS, but that doesn’t mean the U.S. military is planning to stop going after them anytime soon.
“The U.S. military will continue to prioritize and relentlessly target ISIL leaders and external plotters in order to defend our homeland, our allies, and our partners, while we continue to gather momentum in destroying ISIL’s parent tumor in Iraq and Syria and combat its metastases around the world,” Pentagon spokesman Cook said.
Mandy R. asks: In movies they always act like it’s important for a person to stay conscious when they’ve been seriously injured. Does that really help someone live?
We’ve all seen movie scenes where someone is seriously injured and slowly drifting in and out of consciousness. Someone else there will inevitably yell something like, “Stay with me DAMMIT!!!” It’s even sometimes explicitly stated that it’s important for the person to stay awake to keep the Grim Reaper away. Towards this end, the person with them may even be shown to slap the person in the face and/or shake them in an attempt to keep them conscious. This all brings us to the question of the hour — will staying conscious provide any benefit to someone who is seriously injured as depicted almost universally by Hollywood?
Well, no, not really.
In fact, unconsciousness may even mildly help in some cases. For example, one study, Tightly coupled brain activity and cerebral ATP metabolic rate, published in Proceedings of the National Academy of Sciences USA, showed when rats were intentionally knocked out, they produced about 50% fewer ATP molecules. (ATP being the energy that cells use to perform all their vital functions.) The net result of all of this was about a 66% reduction in energy requirements by the brain — potentially a very good thing if your body is already low on the necessary resources to keep on keeping on.
That said, there is one caveat here — being awake while you’re potentially succumbing to your demise can be very helpful for a medical provider in some cases. Namely, if it’s not obvious what’s wrong with you, you being able to communicate the cause of your situation, the specifics of the pain you’re in, or any pertinent history of the problem will help them more easily figuring out the best way to treat you as rapidly as possible, which may make all the difference.
However, other than those benefits, when it comes to staying alive, being conscious isn’t a requirement in any way. Further, your level of consciousness and the change in it actually guides how an emergency provider will treat you, via the Glasgow Coma Scale.
First published by neurosurgery professors Graham Teasdale and Bryan Jennett in 1974 from the University of Glasgow, the scale is used to describe how impaired someone’s consciousness actually is. It assesses a patient according to three general criteria: four parts for eye-opening, five parts for verbal response, and six parts for motor response.
As an example, we have the commonly known phrase in emergency medicine “A GCS less than 8, intubate”. This basically just means that if your score is less than 8, your chance of maintaining your own airway for breathing is so low that it is recommended, and generally an extremely good idea, to stick a tube into the patient’s trachea and take over breathing for them.
Should someone have a score of 14 (confused, but otherwise normal), then all of the sudden have a score of 9 (the level at which Hollywood would have you slapping them incessantly), this would indicate a significant thing just happened and the provider will need to re-evaluate the treatment strategy and confirm or disprove what they think is going on.
Now, given that understanding the vast number of things that can cause someone to become unconscious will only illustrate one of them by putting you all into an incredibly deep sleep, let’s instead just talk about the high level generalities of the two main causes of unconsciousness pertinent to the topic at hand. When someone is potentially dying, it’s because of one of two things — traumatic injury or medical issue.

Looking at the source of most Hollywood movie plot-line unconsciousness, trauma, the two main things that will make you become unresponsive are exsanguination (bleeding out) and traumatic brain injury.
In the former case, if you were able to stay awake when bleeding to death, you simply would naturally — slapping or shaking not needed, nor beneficial. Why? Anytime you’re seriously injured you’re naturally going to have your sympathetic nervous system releasing epinephrine, nor-epinephrine, and dopamine. These hormones will do things like increase your heart rate and constrict your blood vessels and pupils. This results in the greatest amount of blood flow to your brain possible given the circumstances.
Along with this, whether conscious or not, your baroreceptors also continue doing their thing. Residing in an area of your carotid sinus (the beginning of your internal carotid artery) and in the arch of your aortic artery, these handy little mechanoreceptors sense a change in blood pressure and cause the body to react accordingly. Too high a pressure and it will inhibit your fight or flight nervous system (sympathetic). This allows acetylcholine, the main neurotransmitter for your rest and digest nervous system (parasympathetic) to slow down your body’s heart rate and dilate its blood vessels, thereby decreasing your blood pressure.
On the flip side, if they sense too little pressure, like when your precious blood volume is being spilled onto the ground, it will stimulate your sympathetic nervous system to increase its heart rate and constrict blood vessels, raising your blood pressure.
Thus, slapping that person in the face and yelling at them to “Stay with from the light!!!”, will likely only see the medical professionals who arrive slap you in the face for potentially further injuring someone who is already barely clinging to life. That’s not to mention that while you were doing that, you were not doing what you should have been doing — applying direct pressure on the area of bleeding, which is easier and requires far less pressure than you might think to stop the bleeding, even for arterial bleeds.
And it’s not like direct pressure is rocket surgery. It involves simply taking your hand (hopefully gloved, or with some sort of barrier device to prevent the spread of disease) and placing it directly over the wound. Apply enough force to stop the bleeding. Even in the worst types of bleeding, you won’t need more than 3-4 pounds per square inch or about 27 kPa.
You should also have tried to immobilize any body part that looks out of place, so as not to have its movement cause any more damage. Thus, shaking or slapping the individual in a vain attempt to keep them conscious for… reasons we guess… is a bit counterproductive.
Moving on, should the cause of the unconsciousness be a traumatic brain injury (TBI), like a concussion or a bleed in the brain, slapping the person will at best do nothing and may well serve to make the injury worse. Further, shaking or slapping someone with a TBI also comes with the potential risk of damaging their spinal cord.
Moving on to medical reasons for an altered level of consciousness, the causes are vast and can be difficult to nail down. There isn’t always an obvious reason like in trauma where you might see the bullet holes or the bones sticking out of the skin. In fact, there are so many that emergency medical providers use handy little acronyms like AEIOU-TIPS to make sure they’re thinking about all the potential causes when they’re treating you.
A= things like alcohol and acidosis.
E=things like epilepsy, electrolyte abnormalities and encephalopathies.
I= infection (infection being the #1 cause of altered mental status in the elderly).
O=things like overdose or oxygen deficiency.
U= things like underdosing of medications or uremia.
T=trauma or tumors.
I= insulin problems like in the case of diabetes.
P= things like poisons or psychosis
S= things like stroke or shock.
In any of these cases and so many more, the only thing forcing the person to stay awake will do is allow them to give a better history on what is potentially causing their problem. This can be incredibly helpful at speeding up optimal treatment. But it isn’t specifically going to help reverse the actual issue as is usually depicted in cinema, nor is your shaking or slapping going to aid at keeping them conscious anyway. Just like in trauma, in all of these cases, the body already has compensatory mechanisms in place that will keep the person conscious if it can.
In the end, knowing a person’s body is already doing everything it can to stay away from the light, maybe instead of slapping them, just remember — direct pressure, immobilization, call for emergency medical aid, and, when all else fails, just lean down, smile, and say, “Look at me. We’re gonna be okay. You can rest now…” And maybe throw in a “I love you 3,000” just for good measure. You never know, it might just be your last chance to say it.

The most expensive weapons system in history, the US’s F-35 Lightning II, is still sometimes losing to the 1970s F-15 in dogfights during training scenarios in Japan.
US Air Force F-15 pilot Capt. Brock McGehee, when asked by Defense News if the F-35s at Kadena Air Force base in Japan still sometimes lost to the Cold War-era fighters, said “I mean, sometimes.”
The F-35 has long been plagued by reports of that it can’t dogfight as well as older, much cheaper jets, despite being in development for nearly two decades and claiming to revolutionize air combat.
In 2015, War is Boring published a report from a test pilot that said the F-35 couldn’t turn or climb fast enough to keep up with older jets, and F-16s lugging heavy fuel tanks under wing still routinely trounced it.
But a lot has changed since 2015. The F-35 has had its software upgraded and the tactics refined.
Why the Cold War jets can still pull a win out — for now
Retired US Marine Corps Lt. Col. David Berke previously told Business Insider that the older jets benefited from decades of development and training, whereby new pilots today have established best practices. As the F-35 is still in its early days, Berke said the best is yet to come.
“The biggest limitation for the F-35 is that pilots are not familiar with how to fly it. They try to fly the F-35 like their old airplane,” Berke said.
But the pilots at Kadena dogfighting against F-15s may be a cut above, according to Berke, who said that because they have never flown a legacy jet before, they won’t bring the bad habits with them, and will instead learn how to fly the F-35 like the unique plane it is. “They’re going to be your best, most effective tacticians,” Berke said.

“The F-35 cannot out dogfight a Typhoon (or a Su-35), never in a million years,” Justin Bronk, a combat aircraft expert at the Royal United Services Institute, previously told Business Insider.
The reason why, according to Bronk and other experts on the F-35, is that the F-35 just isn’t a dogfighter. The F-35’s stealth design put heavy demands on the shape of the aircraft, which restricted it in some dimensions. As a result, it’s not the most dynamic jet the US could have possibly built, but it doesn’t have to be.
Berke, an alumnus of the US Navy’s famous Top Gun school, echoed Alpert’s assessment, but warned that the common perception of dogfighting was “way off,” and something US jets haven’t done in 40 years. Berke disagreed with Bronk’s “never in a million years” assertion, but maintained that the dogfighting issue was basically irrelevant.
The bottom line is that in training, all jets lose “sometimes.” That the F-35 can hold its own and beat a jet refined over four decades to excel exclusively at air-to-air combat — when the F-35 has been designed to fight, bomb, spy, and sneak — shows its tremendous range and potential.

Former Navy SEAL commander Leif Babin knows that, as a leader, it can be difficult to keep an ego in check. But it’s necessary.
“As a leader, you’ve go to be decisive, you’ve got to make calls, you’ve got to be ready to step up and lead even in the most difficult circumstances,” he told Business Insider. “And yet, if you want to be the most effective leader, you absolutely have to be a follower as well.”
Babin was one of two platoon leaders reporting to Jocko Willink, who led US Navy SEAL Team 3 Task Unit Bruiser in the Iraq War. The two founded the leadership consulting firm Echelon Front in 2010, and their firm has worked with more than 400 businesses.
In their new book, “The Dichotomy of Leadership,” Babin shares a story of a mission that illustrates his point of how a leader must also be a follower.
During the 2006 Battle of Ramadi, Babin led a night mission where his SEALs were providing cover for Army soldiers and Marines. The late Chris Kyle, of “American Sniper” fame, was Babin’s point man. At one point, the team gathered on a roof to determine where they would set up a sniper overwatch. Babin and his leaders decided they would move to a certain building for that, but Kyle countered with a different selection that was not close to Babin’s choice.
Babin outranked Kyle, but he also recognized that Kyle had the most experience with sniper missions of anyone on the team, including himself.
“‘Leading’ didn’t mean pushing my agenda or proving I had all the answers,” Babin wrote. “It was about collaborating with the rest of the team and determining how we could most effectively accomplish our mission. I deferred to Chris’ judgment.”
It was a call Babin said turned out to be the right one, and led to a successful mission. In the book, Babin reflected on a moment when he was a fresh platoon leader, and a stubborn refusal to acknowledge a suggestion from a team member who was lower in rank but had more experience led to a failed training exercise. It was fortunate he learned the lesson before deploying.
“Had we gone with my initial choice — had I disregarded Chris and overruled him because ‘I was in charge’ — we would have been highly ineffective, disrupting virtually no attacks, and that might very well have cost the lives of some of our brethren,” Babin wrote.

I recently had the pleasure to read through the GoRuck Rucking White Paper. It’s basically 18,000+ words on everything you could ever want to know about moving long distances with weight on your back. A topic I am fond of reminiscing about.
Besides telling you to give it a read, print it out, and post it on your unit’s knowledge board I figured I would pull some of the greatness out of it for you as a nice preview of what to expect.
Looks way better than going for a “jog”.
On running in general
“And running sucks anyway, and the worst run is the first run, so there’s that.”
It sucks, but it’s an occupational hazard for many of you. The paper does an eye-opening job of explaining that rucking is actually a lower burden on the body in general when compared to standard running.
On Progressive Overload
“When I was a kid I thought that if I was going to start something new I needed to conquer Rome in a day…That’s not the approach we’re going for here. Your body needs to get used to the effects of a little extra weight on your back, then you need to back off and see how your body responds.”
Sound logic anyone can get behind.
Ruck it out.
“Move a mile with the same rucksack on, and you’ll notice that the last thing you want to do is collapse onto your front. The rucksack literally pulls your shoulders back.
Which is exactly where they should be.”
The argument can be made that rucking will destroy your back and posture. The white paper very smart responds with:
“Form, bitch.” (“my words, not theirs.”)
Like all things, including staring at your phone screen all day, rucking could cause back issues…IF YOU’RE DOING IT WRONG.
In fact, when all the great gouge in this document is applied a proper diet of rucking and beer (more on that shortly) will make you stronger, more resilient, and more posturally erect.
This is the same argument I use when explaining the benefits of the deadlift or back squat to anyone.
There is a huge difference between doing something and doing it properly.
You can eat spaghetti through your nose, sure, but there’s a better way that’s much less likely to deviate your septum.
On working out solely to “look good”
“The point is not to have a set of pretty abs so you can take mirror selfies. One of our Cadre taught me with a smile on his face a long time ago that only an asshole brings a six-pack to a party.”
Just an example of the types of life advice you can expect from the paper.
Log PT is always more fun with friends.
On #slayfest workouts
“Rucking goes counter to the online world of individualized fitness, and counter to the idea of fitness as punishment. Grab your ruck, put some weight in it, and go for a walk. It’s that simple, and it’s more fun with friends and when you’re done, don’t worry about how many calories are in your beer. How’s that for a change of pace?”
One thing is overwhelmingly clear from this paper. You aren’t going to be able to fill up your pack with 100lbs of weight and ruck 6-minute miles for 50 miles on day one. You’ll probably never get to that point.
Who would want to anyway? That sounds miserable even if you are physically capable of it.
The community the folks at GoRuck have garnered is about community, healthy lifestyle, and enjoying a brew. Not necessarily in that order. It’s not about being the hardest hammer in the shed.
There’s a time and place for 150% efforts once in a while. It’s not every day.
On what rucking actually is…
“Ruck Running — don’t do it. That’s one of the only main things I was always told. If you do, all of the risks from running are magnified, and it turns the low injury risk activity of rucking into the high injury risk activity of running…. But, there is a way to move faster than just walking, with a ruck on.”
I have a brief history of rucking. I did not know this.
When first reading through the section on proper form, I just shook my head at how foolish I was.
You live and you learn, I suppose.
Do yourself a favor and learn here before you try to live it.
Rucking is not running. Learn the form, and it will become slightly more enjoyable and a whole lot nicer on your joints.
Pizza. That is all.
On experience being a great teacher
“My feet had blisters on the underside, I had wanted to test out our new boots so I thought it would be a good idea to not change my socks the entire time even though it was a monsoon the night prior and they were wet for over nineteen hours. It was a poor choice. My thighs and my calves ached, and all I really wanted to do was sit on the ground and eat my pizza.”
I truly believe that Dominos may be the only thing on planet Earth calorically dense enough to replenish all of the lost nutrients after a 12+ hour effort.
Been there. Don’t regret it.
On the intention behind GORUCK
“What I never wanted the GORUCK Challenge to become was some sort of bootcamp. Been there, done that, don’t need to do that again.”
I was pleasantly surprised to see this. Bootcamp style fitness is only effective in the short run. Since rucking is a long-run activity (pun intended,) they have their heads in long term adherence.
It has science, humor, history, military doctrine, and no-nonsense logic.
If your unit has you moving any distance with weight on your back, this should be required reading.
Oh, one last quote…
On post-workout beers
“…I started calling Beer ACRT, for Advanced Cellular Repair Technology. People seemed to get it immediately, especially when we’d be done with a Challenge and then I’d crack open a case of beers and start passing them out.”
Northern Afghanistan is at risk of falling to the Islamic State. Their latest attack in Sar-e Pul Province killed 15 Taliban fighters at prayer, but it’s just the latest in a series of ongoing conflicts that have seen hundred killed on both sides. The ISIS stronghold in Nangarhar Province is pushing westward in an effort to undermine the al-Qaeda-affiliated Taliban there.
All the groups involved in the fighting, including those who support the Ghani government in Kabul, are having the same logistical and intelligence problems faced by anyone fighting in the mountainous country — fighters and civilians switch their allegiances as often as their clothes.
The two terrorist groups are vying for power in the country’s eastern and northern regions. The Taliban want to push the Islamic State out of the country before it can establish a clear footprint. In June 2018, the Taliban launched two sweeping offensives in Kunar and Laghman. ISIS, for its part, did not observe the recent three-day ceasefire for the Eid al-Fitr holiday observed by government and Taliban troops.
The black represents ISIS support as of December 2015.

It was during that holiday, the holiest of days for the world’s Muslim population, that ISIS killed 25 in a suicide car bomb attack in Nangarhar. According to The National, a newspaper based in the United Arab Emirates, ISIS sources say the recent Taliban advances were effective and that the Islamic State is experiencing “setbacks” in the rocky provinces of Kunar.
Fighters from Islamic State arrived in force in Afghanistan in 2015, just as ISIS fortunes in Iraq and Syria started to turn sour. The strength the group projected outside the country in recent years invited many defections from other terrorists groups and militias, especially from the Pakistani Taliban. The Afghan Taliban and ISIS have been butting heads ever since.
The Taliban dislikes the Islamic State’s brand of Islamic fundamentalism.
A lot. A whole lot.
ISIS hates that the Taliban draws its legitimacy through ethnic and nationalistic foundations, not Islamic jurisprudence like the kind declared by the Islamic State. To ISIS, Afghanistan is a province they call “Khorasan” and subject to the rule of their self-proclaimed caliphate. The Afghan Taliban’s alliances with Pakistan’s intelligence services and even Shia Muslims are just a few more reasons ISIS declares the Taliban to be non-Muslim nationalists.
There will be no possibility for peaceful resolution between the two.
The guided-missile destroyer USS Chung-Hoon (DDG 93) interdicted a shipment of narcotics aboard a stateless vessel while conducting maritime security operations in the international waters of the Gulf of Aden, Dec. 27, 2018.
Chung-Hoon’s visit, board, search and seizure (VBSS) team seized over 11,000 pounds of hashish while conducting a flag verification boarding.
“We have been conducting maritime security operations along suspected maritime smuggling routes in order to interdict illicit shipments into Yemen and Somalia,” said U.S. Navy Cmdr. Brent Jackson, commanding officer of Chung-Hoon. “It’s critical in an effort to curb the ongoing shipments of illicit weapons and narcotics. I am grateful that Chung-Hoon was able to play a small part in an ongoing effort to deter and limit these illicit shipments of contraband.”

The vessel was determined to be stateless following a flag verification boarding, conducted in accordance with customary international law. The vessel and its crew were allowed to depart once the narcotics were seized.

Chung-Hoon is one of the many ships currently conducting maritime security operations in the U.S. 5th Fleet. Maritime security operations as conducted by the U.S. Navy entail routine patrols to determine pattern of life in the maritime as well as enhance mariner-to-mariner relations. The relationships built as a result allow the U.S. Navy to disrupt the transport of illicit cargo that often funds terrorism and unlawful activities, and also reassures law-abiding mariners in the region.

Chung-Hoon is deployed to the U.S. 5th Fleet area of operations in support of naval operations to ensure maritime stability and security in the Central Region, connecting the Mediterranean and the Pacific through the western Indian Ocean and three strategic choke points.

The U.S. 5th Fleet area of operations encompasses nearly 2.5 million square miles of water area and includes the Arabian Gulf, Gulf of Oman, Red Sea and parts of the Indian Ocean. The region is comprised of 20 countries and includes three critical choke points at the Strait of Hormuz, the Suez Canal and the Strait of Bab-al-Mandeb at the southern tip of Yemen.
The US Navy and regional allies have reportedly noticed an increase in Chinese radio queries to foreign ships and planes operating in the South China Sea — some said to be less than friendly, and others actually threatening.
“Leave immediately,” Chinese forces in the disputed Spratly Islands warned in early 2018 when a Philippine military aircraft flew close to a Chinese outpost, The Associated Press reported July 31, 2018, citing a new Philippine government report.
“Philippine military aircraft, I am warning you again, leave immediately or you will pay the possible consequences,” the report said the Chinese forces threatened soon after, according to the AP.
In the latter half of 2017, Philippine military aircraft patrolling near contested territories received at least 46 Chinese radio warnings, the government report says, according to the AP. While these warnings have traditionally been delivered by Chinese coast guard units, they’re now thought to be broadcast by personnel stationed at military outposts in the South China Sea, the news agency reported.

“Our ships and aircraft have observed an increase in radio queries that appear to originate from new land-based facilities in the South China Sea,” Cmdr. Clay Doss, a representative for the US 7th Fleet, told the AP.
“These communications do not affect our operations,” he added, noting that when communications with foreign militaries are unprofessional, “those issues are addressed by appropriate diplomatic and military channels.”
The Philippine military tends to carry on with its activities. “They do that because of their claim to that area, and we have a standard response and proceed with what we’re doing,” Philippine air force chief Lt. Gen. Galileo Gerard Rio Kintanar Jr. told the AP.
Though an international arbitration tribunal sought to discredit China’s claims to the South China Sea two years ago, China has continued to strengthen its position in the flashpoint region.
In recent months, China has deployed various defense systems — such as jamming technology, surface-to-air missiles, anti-ship ballistic missiles, and even heavy bombers — to the South China Sea, leading US Secretary of Defense Jim Mattis in June 2018 to accuse China of “intimidation and coercion” in the waterway.

Beijing, however, argues that it has a right to defend its sovereign territory, especially considering the increased frequency of US Navy freedom-of-navigation operations in the area; it has conducted more than half a dozen since the start of the Trump administration.
Despite Chinese warnings and objections, the US military has repeatedly made clear that it will maintain an active military presence in the South China Sea.
“International law allows us to operate here, allows us to fly here, allows us to train here, allows us to sail here, and that’s what we’re doing, and we’re going to continue to do that,” Lt. Cmdr. Tim Hawkins told the AP in February 2018.
The US military has also expressed confidence in its ability to deal with China’s military outposts in the region should the situation escalate.
“The United States military has had a lot of experience in the Western Pacific taking down small islands,” Lt. Gen. Kenneth McKenzie, the director of the Joint Staff, told reporters in Ma 2018, adding: “It’s just a fact.”
In early 2018 the US disinvited China’s People’s Liberation Army Navy from participating in 2018’s iteration of the multilateral Rim of the Pacific maritime exercises, citing what it characterized as alarming Chinese activities in the South China Sea. The Philippines has at least twice raised the issue of radio warnings with Beijing, the AP reported July 31, 2018.

The visit — Kim’s first trip outside North Korea since becoming leader in 2011 — came just weeks after Trump agreed to face-to-face talks, for which President Xi Jinping may be able to help Kim prepare.
Lowell Dittmer, a political scientist at University of California Berkeley, told Business Insider that from North Korea’s perspective, China can give Kim crucial insight into the US administration.
China is also potentially being previewed as a potential venue for the historic talks between the leaders, who have not been quiet about their distaste for one another.
Although President Trump has scaled back on his insults against Kim in preparation for the historic talks, Trump has previously referred to Kim as a “little rocket man” and has considered preemptive strikes against the country.
Besides tough talk, Kim is likely concerned about Trump’s style as a negotiator, which has been criticized as “amateur” in the past. Trump has also had some awkward and tense encounters with global leaders in the past, which may explain why Kim could have turned to China for advice on how to handle the US leader.
