Well, wolves will pretty rarely hunt. You're vulnerable if you're on your own or injured. But for lone wolves, get up high, show them that you're not injured, face 'em off, be authoritarian with it, and look 'em in the eye.

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.

I was always brought up to have a cup of tea at halfway up a rock face.

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.

I had many opportunities to get behind products in the past, and I was always careful to evaluate all of them. I will not put my name to shoddy items.

You only get one chance at life and you have to grab it boldly.
