The science of washing your hands (no religion, no goth)

About time you learned you can't trust many of those "scientific" articles you read.

There's a world of difference. Try washing your hands with cold water when they have grease and oil on them after working on your car.
They say Arkansas. If it was invented anywhere else, it would have been called the teethbrush.
