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.

Nobody else is stupid enough to get themselves into the straits that I get into.

Never depend on those luck moments – they are gifts – but instead always build your own back-up plan.

Change the way you use your time, and you change your life.

Exercise helps my back. If I don't exercise, that's when it starts to hurt. The pain is a good motivator to run and exercise.

I always wanted to be Robin Hood or John the Baptist when I was growing up.

Weather can kill you so fast. The first priority of survival is getting protection from the extreme weather.
