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.

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.

Look, sometimes, no matter how hard you try, sometimes you need a bit of luck.

Survival requires us to leave our prejudices at home. It's about doing whatever it takes - and ultimately those with the biggest heart will win.

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

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.

Never depend on those luck moments – they are gifts – but instead always build your own back-up plan.
