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.
