Endure In Endure Alex Hutchinson, Ph.D., reveals why our individual limits may be determined as much by our head and heart, as by our muscles. He presents an overview of science’s search for understanding human fatigue, from crude experiments with electricity and frogs’ legs to sophisticated brain imaging technology. Going beyond the traditional mechanical view of human limits, he instead argues that a key element in endurance is how the brain responds to distress signals―whether heat, or cold, or muscles screaming with lactic acid―and reveals that we can train to improve brain response. The Rise of Superman Right now, more people are risking their lives for their sports then ever before in history. As Thomas Pynchon once put it in Gravity's Rainbow, 'it is not often that Death is told so clearly to f@%* off'.Over the past three decades, the bounds of the possible in action and adventure sports - from sky-diving to motocross to surfing and beyond - have been pushed farther and faster. A generation's worth of iconoclastic misfits have rewritten the rules of the feasible; not just raising the bar, but obliterating it altogether. Along the way, they have become a force pushing evolution relentlessly onward.
