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.

Why is it that the finish line always tends to appear just after the point at which we most want to give up? is it the universe's way of reserving the best for those who can give the most? What I do know, from nature, is that the dawn only appears after the darkest hour.

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

I do see a lot of the hard end of ecology, and my feeling is that we live on a super-exciting planet but a super-fragile one.

I think fire is so critical in the wild. You can cook with it, you can make tools, you can deter a predator, you can dry your clothes and you get that element of morale that matters so much when you're stuck in the middle of nowhere.

Survival can be summed up in three words - never give up. That's the heart of it really. Just keep trying.

I try and eat really healthy when I'm home, but I certainly don't eat worms and snakes.
