It's important to have a dream no matter how old you are.
If the limit of age 80 is at the summit of Mt Everest, the highest place on Earth, one can never be happier.
It's important to set your own goals and work hard to achieve them.
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.
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.
