Our fate is determined by how far we are prepared to push ourselves to stay alive - the decisions we make to survive. We must do whatever it takes to endure and make it through alive.

As a young boy, scouting gave me a confidence and camaraderie that is hard to find in modern life.

It's unresolved conflict in my life that I have a lovely family and a risky job.

I've fallen down crevasses, been bitten by snakes, been knocked unconscious, had various limbs broken and once, a heavy camera came plunging down which very nearly decapitated me.

I do see a lot of the hard end of ecology, and my feeling is that we live on a super-exciting planet but a super-fragile one.

Time and experience have taught me that fame and money very rarely go to the worthy, by the way - hence we shouldn't ever be too impressed by either of those impostors. Value folk for who they are, how they live and what they give - that's a much better benchmark.

Sometimes an ember is all we need.
