So, yahoo posted an awesome article debunking some travel myths. I'm not sure which of the debunkings was my favorite - the one that says that recirculated air on a flight won't make you sick or the one that says that it's neither illegal or dangerous to use a cell phone when you fly.
Except for one thing, cell phones are annoying. Can you imagine a planeload of people on an airplane chatting on their phones for the whole flight? It would be worse than a New Jersey transit train. My theory? The airlines keep the bogus rule to keep people from annoying each other or giving out too much information.
