One thing we learned was that when you wash your hands, you wash of a layer of bacteria (good and bad!) then your body just pops out another layer of bacteria to protect you. Cool huh?

The hand sanitizers and antibacterial soaps do get rid of that first layer of bacteria, but they linger so that new batch of bacteria doesn't live when it pops out to protect you. On top of that, anything you touch leaves behind the residue, which, yes, does allow microbes to mutate.

It's all kinda gross but so cool.
