Abstract

All of us had fallen from 100 stories.Falling is rarely a good thing. It is something to avoid for safety, and such avoidance, for those of us fortunate enough to be in good health, has been burned into the unconscious memory of our muscles and bones. Unless we find ourselves in high places, or on some kind of precipice, falling tends not to be on the mind. It is, most of the time, a surprise.But it is also always a possibility, in part because of one of those characteristics that define the human—our upright posture. Without this trait that.
