That feeling when you're so cold you'd give anything to be warm - I've had it before, literally huddled around a candle flame on an ice sheet.

You only get one chance at life and you have to grab it boldly.

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.

Survival can be summed up in three words - never give up. That's the heart of it really. Just keep trying.

One killer exercise that's really great is pull-ups with your legs out level. That's my favourite. It's such functional core strength, and that's why I can climb up trees and down vines.

I don't like expeditions where it is a total lottery whether you live or die. You have to keep those sort of good luck cards for rare occasions!

I try and eat really healthy when I'm home, but I certainly don't eat worms and snakes.
