....STOP TOUCHING YOUR DAMN FACE!
You probably don't realize how much you touch your face. I just touched my face while I was saying that. And during this particularly NASTY flu season, you really SHOULD try to pay attention.
Apparently, a good way to keep yourself from getting the flu is to stop touching your face so much.
The average person touches their face three times an hour. And since you're not washing your hands three times an hour, you may be infecting yourself with the germs on your hands without even realizing it.
