I joined the Army at 19 as a soldier and spent about four and a half years with them. Then I broke my back in a freefall parachuting accident and spent a year in rehabilitation back in the U.K.

I find skydiving really hard. I broke my back while skydiving when I was in the military, and for 18 months all my nightmares were about falling.

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

My work is all about adventure and teamwork in some of the most inhospitable jungles, mountains and deserts on the planet. If you aren't able to look after yourself and each other, then people die.

Exercise helps my back. If I don't exercise, that's when it starts to hurt. The pain is a good motivator to run and exercise.

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