I don't like expeditions where it is a total lottery whether you live or die. You have to keep those sort of good luck cards for rare occasions!

For me, my training is a key part of my work as so often my life has depended on being able to move fast and haul myself up and out of something fast!

I love making healthy lean foods delicious - that's an art!

I'm terrified of walking into a room full of people. Sitting down at a dinner table with 15 strangers brings me out in a sweat.

I don't thrive on stress. I love lying on the deck on our houseboat reading a book.

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.

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

Accidents on big mountains happen when people's ambitions cloud their good judgment. Good climbing is about climbing with heart and with instinct, not ambition and pride.

You can't live someone else's expectations in life. It's a recipe for disaster.

The truth is, I need 10 lifetimes to scratch the surface of the things I'd love to do.

Our fate is determined by how far we are prepared to push ourselves to stay alive - the decisions we make to survive. We must do whatever it takes to endure and make it through alive.

I had many opportunities to get behind products in the past, and I was always careful to evaluate all of them. I will not put my name to shoddy items.

The line between life or death is determined by what we are willing to do.

The SAS Reserve tends to be made up of former paratroopers and commandos who still want a challenge, but it is open to civilians.

I come from a line of self-motivated, determined folk - not grand, not high society, but no-nonsense, family-minded go-getters.

Being brave isn't the absence of fear. Being brave is having that fear but finding a way through it.

Adventure should be 80 percent 'I think this is manageable,' but it's good to have that last 20 percent where you're right outside your comfort zone. Still safe, but outside your comfort zone.

When I'm in 'Man vs. Wild' mode, it's not pleasure. Every sensor is firing and I'm on reserve power all the time and I'm digging deep - and that's the magic of it as well, and that's raw and it's great.

I was always brought up to have a cup of tea at halfway up a rock face.

To get ready to climb Everest, I did a lot of hill running with a daypack on and a lot of underwater swimming. I would swim a couple of lengths underwater and then a couple above. It gets your body going with limited oxygen.

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.

I think it's fun running with dogs. They're always so fit and fast.

In the British Special Air Service, combat fitness is all about running.

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.
