Seriously. Ask any elementary school teacher you know how often they and their families get sick - it might well be an order of magnitude more than other people. It's pretty possible to avoid (contagious) illness for a year at a time if you don't have kids and don't spend time at schools/campuses/conventions. Change one of those things and you'll be sick in a month.
