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've eaten sheep's eyes, the still hot meat from a zebra killed by a lion, and maggots which give you 70 calories to the ounce.

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.

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

I loved climbing because of the freedom, and having time and space. I remember coming off Everest for the last time, thinking of Dad and wishing that he could have seen what I saw. He would have loved it.

The rules of survival never change, whether you're in a desert or in an arena.

Live a wild, generous full, exciting life – blessing those around you and seeing the good in all.
