My immune system is weird. I can go for years without getting sick, and then catch "that little cold that's going around" and be in bed for a week with it. If I get a little sick at the beginning of flu season, it'll usually skip me when everybody else is really sick, so I tried to give myself the swine flue back in august. I had a sniffle, but I'm not sure if it was H1N1 or just this year's seasonal. Well, it'll either skip me, or I'll die.
