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.

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.

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

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 hang out all the time with kids and young scouts and I never meet kids who don't want adventure.

Life's full of lots of dream-stealers always telling you you need to do something more sensible. I think it doesn't matter what your dream is, just fight the dream-stealers and hold onto it.

Nobody wants to end up super rich and famous - but divorced. I'm always clear on that and try to stay on the right side of the line.
