Yesterday I was in a long line waiting to go down a water slide at an amusement park. Squeezed in between countless other people in nothing but skimpy bathing suits, it was often unavoidable to glance at their skin. And so I got to thinking, what if I was a dermatologist waiting in that line? I would see all of their moles, sunburns, skin disorders and bug bites. What goes through a dermatologist's head in such a situation? Does he do everything in his power to keep his mind focused on other things, or does he have to resist the urge to tap the person on the shoulder and say, "You know that oddly shaped mole on your left lower back? You should really get that checked out," or maybe he actually does say that to them, possibly handing them his business card and assuring the fellow water slide riders that he can take care all of their skin-related difficulties.
