The rules of survival never change, whether you're in a desert or in an arena.

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

Weather can kill you so fast. The first priority of survival is getting protection from the extreme weather.

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.

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!

When I'm filming, survival requires movement. You need your energy, and you've got to eat the bad stuff, and survival food is rarely pretty, but you kind of do it. I get in that zone, and I eat the nasty stuff, but I'm not like that when I'm back home.
