My earliest memory is being in a snow hole, aged two-and-a-half, with my dad somewhere up a mountain in a blizzard. I don't know what my dad saw in me - I was a geeky kid - but he had that philosophy: prepare the kid for the road, not the road for the kid.

I feel very lucky to be able to call my hobby my job, yet it doesn't feel like one.

I am at a climbing area called the Wendenstock in Switzerland. This area has some of the best quality multi-pitch climbing I have seen on limestone. There is about a two-hour approach on one of the steepest grass slopes I have ever seen. The setting is amazing.

There are specific things in our world that are incredibly dangerous. Wingsuit BASE jumping is the very, very top of that. Big alpine climbing objectives are maybe right below that. I've probably had 20 friends die - people who were pretty close to me. I would say about 18 of them were because of snow.
