When I'm in 'Man vs. Wild' mode, it's not pleasure. Every sensor is firing and I'm on reserve power all the time and I'm digging deep - and that's the magic of it as well, and that's raw and it's great.

I'm terrified of walking into a room full of people. Sitting down at a dinner table with 15 strangers brings me out in a sweat.

The only difference between 'try' and 'triumph' is varying degrees of 'umph'

I've seen extreme bravery from the least likely of people. Life is about the moments when it's all gone wrong. That's when we define ourselves.

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.

The line between life or death is determined by what we are willing to do.

I train five days a week hard - but it is short and sharp - 30 to 40 minutes of functional and pretty dynamic body-strength circuits, then I do a good yoga session on the sixth day, then I rest.
