The hardest thing about my job isn't the snake bites or the crocodiles, it's being away from my children. I have a really religious satellite phone call every day back to the boys, wherever we are, whatever time zone, to say goodnight.

Americans are cool, if you show just a chink of vulnerability, they respond so much. They'll pat you on the arm and say, 'Hey kid, you're all right'. Brits will respond but they are much more cynical.

The extremes of jungles, mountains, and deserts are inherently dangerous places.

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 hang out all the time with kids and young scouts and I never meet kids who don't want adventure.

The rewards of the wild and the rewards of the survivor go to those who can dig deep, and, ultimately, to the guy who can stay alive.

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.
