Travis Stork, M.D., emergency medicine physician and host of TV's "The Doctors", recently tweeted that before he became a doctor he used to get colds all the time.
And the bad news is that proper handwashing still eludes many of us, he says.
"Before I became a doctor I just ran some water over them," he said during a recent HuffPost Live appearance. "I could never figure out why I was sick all winter long."
Luckily, a sufficient scrub can go a long way in cold and flu prevention, he said. Just make sure you're washing well: Continue rubbing a soapy lather for at least 20 seconds, about as long as it should take you to hum "Happy Birthday" twice through, according to the CDC.
