Why do men.....

Okay, maybe this isn't the most PC post but after reading today's Sanders Says post about washing your hands, I've been thinking about it. Why is it that some/most men do NOT wash their hands after visiting the restroom? Twice today I noticed this. Now, I can see while going #1 you could sorta rationalize and say, "hey, I don't pee on my hands" but #2? Give me a break? Let's start a compaign, "Wash your hands!", I don't want your germs.
