Christianity is not about religion. It's about faith, about being held, about being forgiven. It's about finding joy and finding home.

I love home cooking, and I'm not a great one for fast food.

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

I exercise about 40 minutes a day, and I'll run one day and do circuit training the next day. I live in an area where there are brilliant hills and mountains, so I get a good hill run with my dog. At home, I'll do the circuit training with old weights, along with pull-ups in the trees and that sort of stuff.

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.

Survival requires us to leave our prejudices at home. It's about doing whatever it takes - and ultimately those with the biggest heart will win.

Christianity is not about religion. It's about faith, about being held, about being forgiven. It's about finding joy and finding home.

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

My faith isn't very churchy, it's a pretty personal, intimate thing and has been a huge source of strength in moments of life and death.

One killer exercise that's really great is pull-ups with your legs out level. That's my favourite. It's such functional core strength, and that's why I can climb up trees and down vines.
