Some people loathe that electrifying buzz of fear, while others crave it.
I just heard a report on National Public Radio about a retired firefighter who, on his own, battled the blazes that threatened a small town in Washington. That's my job. There's a man who thrives on adrenaline and a need to serve others, along with people in many other professions, from Navy SEALs to rescue workers. But while they live for the buzz of fear, their jobs depend upon their being able to dominate it. They learn that to survive a physical threat, they must not act on instinct, but on cool rationality.
