in reply to OT: Wash hands after computer use.

do not subconciously rub your eyes, ears, or nose until you wash your hands

/me puts his hands covering his ears and says "Oh no! What have I done?"

And then he rubs his eyes: "Maybe this is just a dream."

...

Hum... my nose is itching...

(as Jaap, I'm only kidding; I too feel this is important advice
