I come from a line of self-motivated, determined folk - not grand, not high society, but no-nonsense, family-minded go-getters.

I've fallen down crevasses, been bitten by snakes, been knocked unconscious, had various limbs broken and once, a heavy camera came plunging down which very nearly decapitated me.

As a young boy, scouting gave me a confidence and camaraderie that is hard to find in modern life.

My faith is an important part of my life and over the years I've learnt that it takes a proud man to say he doesn't need anything. It has been a quiet strength and a backbone through a lot of difficult times.

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

It breaks my heart that my father never knew my children. He should have been around for another 25 years.

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.
