Skiing down Mount Everest
Forty years ago, Yuichiro Miura skied down Mount Everest.
"When I planned to ski Everest, the first thing I faced was 'How can I return alive?'" he recalls. "All the preparation and training was based on this question. But the more I prepared, I knew the chance of survival was very slim. Nobody in the world had done this before, so I told myself that I must face death. Otherwise, I am not eligible."
Miura's exploits were the subject of The Man Who Skied Down Everest, which won the Oscar for best documentary.
