It's unresolved conflict in my life that I have a lovely family and a risky job.
I try and eat really healthy when I'm home, but I certainly don't eat worms and snakes.
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.
To get ready to climb Everest, I did a lot of hill running with a daypack on and a lot of underwater swimming. I would swim a couple of lengths underwater and then a couple above. It gets your body going with limited oxygen.
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.
Textbook survival tells you to stay put. Stop. Wait for rescue. Don't take any risks. But there'd been a whole host of survival shows like that and I didn't really want to do that.
