From the introduction: "In this book I want to look at a wide spectrum of adventurous activities, to see what they have in common, not so much in the motive - the why of it - but rather the 'how'. This book chronicles a goos amount of climbing, but also investigates other disciplines in the oceans, the poles, and the caves of Earth.
