Where does that cold-causing bacteria lurk?

Here's my germ-management system: I wash my hands. Not excessively -- I'm not germaphobic -- but enough to feel like they are generally clean. For most of my life, that plan served me just fine. But last year as the weather got cold, I got a cold. And another cold. And another cold. I didn't stop hauling Kleenex around until spring. It was pure misery.
