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.

My Christian faith is my backbone

The hardest thing about my job isn't the snake bites or the crocodiles, it's being away from my children. I have a really religious satellite phone call every day back to the boys, wherever we are, whatever time zone, to say goodnight.

Both faith and fear may sail into your harbor, but only allow faith to drop anchor.

Some of the greatest survivors have been women. Look at the courage so many women have shown after surviving earthquakes in the rubble for days on end.

A man's pride can be his downfall, and he needs to learn when to turn to others for support and guidance.

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.
