Among these have been an unhealthy number of near-death moments, many of which I look back on now and wince. But I guess our training in life never really ends--and experience is always the best tutor of all. Then there are the most bizarre: like jet-skiing around Britain in aid of the UK lifeboats. Day after day, hour after hour, pounding the seas like little ants battling around the wild coast of Scotland and Irish Sea. (I developed a weird bulging muscle in my forearm that popped out and has stayed with me ever since after that one!) Or hosting the highest open-air dinner party, suspended under a high-altitude hot-air balloon, in support of the Duke of Edinburgh's kids awards scheme. That mission also became a little hairy, rappelling down to this tiny metal table suspended fifty feet underneath the basket in minus forty degrees, some twenty-five thousand feet over the UK. Dressed in full naval mess kit, as required by the Guinness Book of World Records--along with having to eat three courses and toast the Queen, and breathing from small supplementary oxygen canisters--we almost tipped the table over in the early dawn, stratosphere dark. Everything froze, of course, but finally we achieved the mission and skydived off to earth--followed by plates of potatoes and duck a l-orange falling at terminal velocity. Or the time Charlie Mackesy and I rowed the Thames naked in a bathtub to raise funds for a friend's new prosthetic legs. The list goes on and on, and I am proud to say, it continues. But I will tell all those stories properly some other place, some other time. They vary from the tough to the ridiculous, the dangerous to the embarrassing. But in this book I wanted to show my roots: the early, bigger missions that shaped me, and the even earlier, smaller moments that steered me.
