I have held healthy respects of bears along with assorted crocodiles, snakes and lots of other animals. You know, bears are dangerous, you have to be super careful.

I train five days a week hard - but it is short and sharp - 30 to 40 minutes of functional and pretty dynamic body-strength circuits, then I do a good yoga session on the sixth day, then I rest.

But the wild is unpredictable, stuff does happen, and it's always when you're least expecting it.

Unless you have shelter, fire is going to be very hard and if you have fire, but no water, you're going to die. They're all super important.

As for my diet, I try to eat lean, clean and healthy - nothing too surprising. And I avoid too much meat or dairy because they slow you down.

I loved climbing because of the freedom, and having time and space. I remember coming off Everest for the last time, thinking of Dad and wishing that he could have seen what I saw. He would have loved it.

Don't be scared to dream big, and don't be afraid to be close to people. And never give up! It's the tenacious not the talented that win.
