Yeah, I'm really germaphobic so I'm always washing my hands and stuff....your picking up a germ somewhere that your body can't fight off --figure out and eliminated the source. I always keep sanitary wipes handy and never touch door handles in public and use my own pens. I have to be a real freak about germs now, (since I had bi-lateral PE's 9 months ago) my body doesn't fight germs the same way for some reason.
