After the outbreak of World War I, young Paul Kern joined millions of Hungarian countrymen in answering the call to avenge their fallen Archduke, Franz Ferdinand. He joined the Hungarian army and, shortly after, the elite corps of shock troops that would lead the way in clearing out Russian trenches on the Eastern front. In 1915, he was shot in the head by a Russian bullet, and he closed his eyes for the last time.
This would be par for the course for many soldiers – except Kern's eyes opened again in a field hospital.
Many, many other Austro-Hungarian eyes did not open again.
From the moment he recovered consciousness until his death in 1955, Kern did not sleep a wink. Though sleep is considered by everyone else to be a necessary part of human life. There are many physical reasons for this – sleep causes proteins in the brain to be released, it cuts off synapses that are unnecessary, and restores cognitive function. People who go without sleep have hallucinations and personality changes. Sleeplessness has even killed laboratory rats.
But for 40 years, Paul Kern experienced none of these symptoms. His biggest issue with being awake for 24 hours a day was the costs associated with being awake and functional for that extra eight hours.
Doctors encountering Kern's condition for the first time were always reportedly skeptical, but Kern traveled far and wide, allowing anyone who wanted to examine him to do so. The man was X-rayed in hospitals from Austria to Australia but not for reasons surrounding the bullet – the one that went through his right temple and out again – was ever found.
One doctor theorized that Kern would probably fall asleep for seconds at a time throughout the day, not realizing he had ever been asleep, but no one had ever noticed Kern falling asleep in such a way. Other doctors believed the bullet tore away all the physical area of the brain that needed to be replenished by sleep. They believed he would find only an early death because of it.
Kern did die at what would today be considered a relatively young age. His wakefulness caused headaches only when he didn't rest his eyes for at least an hour a day in order to give his optic nerve a much-needed break. But since Paul Kern had an extra third of his days given back to him, he spent the time wisely, reading and spending time with his closest friends. It seems he made the most of the years that should have been lost to the Russian bullet in the first place.
