Occasionally some own their survival not to struggle but to simple luck. Take the starting case of Mitsutaka Uchikoshi. One ice-cold October day in 2006 Uchikoshi had been at a party on a mountain in western Japan. After wandering of into a field on his own Uchikoshi tripped hit his head and was knocked unconscious. As Uchikoshi remembers “I was in a field” and I felt very comfortable. That’s my last memory”. He remained unconscious I almost-freezing temperatures without food or water for more than three weeks.
