To get ready to climb Everest, I did a lot of hill running with a daypack on and a lot of underwater swimming. I would swim a couple of lengths underwater and then a couple above. It gets your body going with limited oxygen.

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

For me, my training is a key part of my work as so often my life has depended on being able to move fast and haul myself up and out of something fast!

Always keep the big picture in mind- you are greatly loved by Jesus and your job is to love Him and others in return. The rest is detail.

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.

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

I hang out all the time with kids and young scouts and I never meet kids who don't want adventure.
