It's important to set your own goals and work hard to achieve them.
After retiring, I was a little bored with nothing to do and got fat. I thought, if a 60-year-old metabolic fat man, after five years, can get to Mount Everest, that would be very exciting.
I've been doing extremely dangerous activities for a long time, but I've been lucky enough to have survived so far. However, sooner or later we all die... and, if that's the case, I want to die doing what I love to do the most. That's how I view death.
I never imagined I could make it to the top of Mount Everest at age 80. This is the world's best feeling, although I'm totally exhausted. Even at 80, I can still do quite well.
Just keep challenging yourself. I think that's a great thing.
When I planned to ski Everest, the first thing I faced was, 'How can I return alive?' 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.
