I recently read a book called Between a rock and a hard place by Aron Ralston. It is a very good book and I highly recommend it. The author was rock climbing in Blue John Canyon when a rock shifted, trapping his arm between the rock wall and the boulder. He eventually escapes by snapping his arm and amputating it with his pocket knife. Isn't it amazing what humans will do to survive? Isn't it amazing what people can do with a bit of determination?
