It's unresolved conflict in my life that I have a lovely family and a risky job.

You only get one chance at life and you have to grab it boldly.

I exercise about 40 minutes a day, and I'll run one day and do circuit training the next day. I live in an area where there are brilliant hills and mountains, so I get a good hill run with my dog. At home, I'll do the circuit training with old weights, along with pull-ups in the trees and that sort of stuff.

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.

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

The appeal of the wild for me is its unpredictability. You have to develop an awareness, react fast, be resourceful and come up with a plan and act on it.

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