Elbow sweat can be fatal. It’s true! Forget about the diseases carried by sweat bees (which are totally real and disgusting insects that I did not make up and are attracted to sweat, but will bite when they get trapped in your knee pit or inner elbow or… elsewhere) but my idiot sister-in-law used to live with a guy who died because of his sweaty arms. Well, hands really… they impeded his ability to grip the metal rail from which he hung. But they wouldn’t have been so slick if he hadn’t been running from the police, would they? No, he fell to his death another tragic victim of exercise.
