What Makes Guys Wash Their Hands…

According to a new study, all it takes to get guys to wash their hands after using the bathroom is a posted sign telling them to do it.

Researchers found that guys claimed to wash their hands 75 percent of the time after doing their bathroom business.

But when signs were posted in bathrooms that read: "4 out of 5 Males Wash Their Hands," the hand washing increased to 86 percent.
