The hardest thing about my job isn't the snake bites or the crocodiles, it's being away from my children. I have a really religious satellite phone call every day back to the boys, wherever we are, whatever time zone, to say goodnight.

I've had so many injuries in my life that it's ridiculous.

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.

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.

A wise man knows; learn from others, never get complacent and know where the classic old dangers come from.

What Scouting says to people is: Every child has a right to have an adventure. Life is about grabbing opportunities

There's no magic to running far or climbing Everest. Endurance is mental strength. It's all about heart.
