A recent study spied on people as they left public restrooms to see if they washed their hands after using the bathroom and surprise of all surprises, men don't wash their hands as often as women. We're dirty vile creatures. Yes, we know.
I'm actually surprised that people at "Atlanta's Turner Field, where 37 percent of the men left the bathroom without washing" were the worst offenders. I recently went to Michigan football game and it seemed like only a third of the guys washed their hands when they were finished.
