My latest concern, likely in response to some incessant commercials on the subject, is the existence of disgusting, invisible dust mites that camp out in our mattresses, living off our skin flakes (yuck!) and generally up to no good.

Allergies were the realm of those brainy, pale, nose-picking girls in middle school who had to run and get shots every time you turned around.
