In nearly every high-risk sport, the mastery of fear comes up repeatedly as the principal reward for engaging in it. The deeper the fear, the bigger the thrill when you cnquer it. One study found that the more frightened sky divers were while going up in a plane, the more exhilarated thay felt when they parachuted safety to the ground.
According to Ralph Keyes, author of the book Chancing It: Why We Take Risks, that rush is delivered by natural opiate-like body chemicals that kick in during a stressful experience. “It’s nature’s way of rewarding us for taking chances,” he says.
Keyes, who interviewed nearly a thousand T-Types for his book, says some people bcome addicted to that chemical kick and look for ever-more-challenging ways to keep it coming. A predisposition to thrill seeking, he adds, may even be genetic.
