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

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

I've never really had a TV career. I've been a soldier and a climber.

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 never wanted to do TV. I just did what I was trained to do through the Special Forces, and I've been doing that from a very young age.

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