Use your paper towel to turn the doorknob in the bathroom

If you use the paper towel as a primitive shield when you turn the knob, or push the door if it's that kind, you're less likely to put new filth on your hands after painstakingly removing the old filth.

This is probably most important if you're preparing someone else's food after leaving the restroom, like, say if you work in a restaurant.

There is, however, one small flaw in the case for the use of paper towels: Recently, I saw a documentary on the TV on the subject of bathroom hygiene, (mental note to self: Must get cable.). The upshot was that the toilet seat is often one of the cleanest places in a bathroom. The door handle has one of the highest levels of bacteria, along with the little handle used to crank the paper towels.

     We need to strenthen our immune system, it's not the filthy ones who get the flu so often if you've noticed. More and more people (especially in lab-condition countries like Japan) weaken their immune system by disinfecting and swabbing everything in sight. When a bacterium does pass through, it goes more or less unhampered in the body, causing rampant infections. Old ladies and people with weak immune systems probably should shield what they have from constant attack. But there is no reason for any healthy individual under fifty to hide out from all the germs the world beholds, put away that anti-bacterial hand lotion before you get yourself sick.
