Jet lag trivia:

Two weeks ago, I had someone tell me that they drink lots of liquids to deal with jet lag...because of the dry air on the planes. Obviously the person does not know what jet lag is. Once in the paper, someone asked if they would have jet lag while flying from N. America to S. America? or flying East coast to West coast and then right back to the East coast? The answer is..NO!...jet lag is your body's inability to rapidly change sleep schedules in order to adjust to a new time zone....it really has nothing to do with actually flying. If a high-speed train went from LA to NYC, you would still have "jet lag"(maybe we would call it "train lag"?).
