I was christened Edward. My sister gave me the name Bear when I was a week old and it has stuck.

You don't often see Bear Grylls in a suit.

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

The special forces gave me the self-confidence to do some extraordinary things in my life. Climbing Everest then cemented my belief in myself.

You're not human if you don't feel fear. But I've learnt to treat fear as an emotion that sharpens me. It's there to give me that edge for what I have 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.
