Jet lag -- Monster or myth?;

              Jet Lag-Monster or Myth?
"If human beings were meant to fly, why don't they have wings?"
"If human beings were meant to fly, why don't they have wings?" So goes an only partially humorous question challenging the idea of air travel. The query, which no doubt originated in the days of Orville and Wilbur, is seldom heard in today's jet-age society. But it may well have given rise to another more pressing question that is currently heard more and more - from doctors and scientists along with mere skeptics. That is, "If human beings were meant to fly, why do they get jet lag?"
Why indeed? With the ever-improving quality of commercial aircraft and the corresponding decrease in flight times, one might assume that the physical discomforts associated with air travel would have decreased accordingly. And so they have - at least while the passenger is still aloft. It's when the long-distance traveler reaches his or her destination that that notorious malady, commonly known as jet lag, rears its Ugly head.
