I got a pretty nasty cold from being outside too long in a temperature that wasn't cold enough to even be able to snow in, last week. It kinda sucks, but these sicknesses help with the immune system don't they? And maybe I'll avoid situations where I have to stand outside for a long time.
I should point out that this is, of course, a south Texas winter; it couldn't have been colder than ~40 degrees. My body's just not used to prolonged periods of that temperature though.
It's gonna suck when I (hopefully) move up north one of these days.
