Fly right

Flying? Turn on the air vent above your seat. "I fly a couple of times a week," says Travis Stork, MD, an emergency medicine physician and co-host of The Doctors. "Part of the way I stay healthy is by being very conscientious about all of the germs that are on planes. I turn on the air vent and angle it so it blows air down in front of my face—that's filtered air and it creates a little bit of a barrier to keep the germs going around the cabin from getting into my nose or mouth."
