Okay, maybe I'm a weirdo here, but I wash my hands after the bathroom, and uh...that's it.
But, for the past 6 months or so, since I've bought new keyboards I care about, and I've gone through and cleaned some of my old crappy ones, I've been mad enough at the board chow and general grossness that I now wash my hands before I use the computer, every day. I get home from work, wash my hands, and go to the computer.
Is it just me? Am I weird?
