...ah, I see. I think I hadn't quite put together that "constantly feeling like you're about to come down with a cold" was the allergies rather than actually catching things.

I may have mentioned before, but I (reportedly) got chicken pox twice. Once when I was a tiny baby, but apparently it somehow didn't give me the antibodies, whether because it wasn't a strong enough case or because it was in fact something else altogether (although it wasn't measles because I did in fact get vaccinated), and then when I was seven.
