“Incidentally, I spent some time on the Purell website, where you can find a list of ninety-nine places germs lurk (in-flight magazines, movie tickets, gas-pump keypads, hotel room a/c controls, and on and on). It's hilarious and terrifying. The only place they don't mention is the Purell dispensers themselves. You know they're coated with germs. It's one of health's cruelest catch-22s.”
