Ever since I almost died on the Matterhorn two years ago, my approach to physical risk has changed.

As a young man, I had an entirely different risk appetite to what I do now. High risk adventure sports – like mountaineering, climbing, racing mountain bikes down hills, skydiving and riding motorbikes were a regular part of my life before a big fall that also finished me.

Now, my appetite to take the same risks has been sated, but for how long – I don’t know for certain. I still dream of big mountains and that feeling of elation when you’re stood on a summit after months of planning and the hours spent plodding uphill.
