My favorite moments? Where it's all going swimmingly, the sun's out and I've got a fire going and a nice snake on the barbecue.

I always wanted to be Robin Hood or John the Baptist when I was growing up.

Sometimes it's hard for us to believe, really believe, that God cares and wants good things for us and doesn't just want us to go off and give everything up and become missionaries in Burundi.

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.

You're not human if you don't feel fear. But I've learnt to treat fear as an emotion that sharpens me. It's there to give me that edge for what I have to do.

When I'm in 'Man vs. Wild' mode, it's not pleasure. Every sensor is firing and I'm on reserve power all the time and I'm digging deep - and that's the magic of it as well, and that's raw and it's great.

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.
