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

How you speak about others speaks loudest about yourself.

I am not fearless. I get scared plenty. But I have also learned how to channel that emotion to sharpen me.

The appeal of the wild for me is its unpredictability. You have to develop an awareness, react fast, be resourceful and come up with a plan and act on it.

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

Survival is not about being fearless. It's about making a decision, getting on and doing it, because I want to see my kids again, or whatever the reason might be.
