Here's a story that can offer hope and gross you out at the same time. Researchers at Michigan State University, asked men about hand washing upon leaving the restroom. The men said they washed their hands 75 percent of the time.
The researchers next posted signs in men's restrooms that read "4 out of 5 Males Wash Their Hands," with pictures of students wearing Michigan State University hats. The signs included details about proper hand-washing.
