At least it is for an educational purpose. In the area of odd and kind of creepy research (not to mention kind of gross for the poor people posted in the bathrooms to observe behavior), some Hunter College undergraduates observed the hand washing behavior of a couple thousand New York City inhabitants. Almost a quarter of them did not use soap when washing their hands, good news for your average public bathroom dwelling germ but bad news for those people. Unsurprisingly, almost 20% of men did not even bother to rinse their hands. Well, what has 1 in 5 New York City men touched before they shook your hand?
