I haven't been ill in years. I'm allergic to cats. I work around cats. I take medication for my allergies. But my allergies have nothing to do with my immune system. So I do get runny nose and sneeze and stuff. But that's it. And that's not my immune system. As far as ailments go, I'm the healthiest person I know >_>; I really hope my heart and blood pressure and stuff are doing just as well.
