I left work today with a few things on my mind and realized that I’d left my helmet on my desk when the elevator hit the ground floor. I hit the button to head back up and wait through the stoppage on each floor. Halfway there, it occurred to me that if I get hit by a bus and the helmet saves my life on my ride home, I likely wouldn’t have been hit by that bus if I’d just ridden home and left my helmet on my desk instead of going back for it. I’m happy to report that I did not get crushed by a bus on the ride home, but if I’d left my helmet and just ridden home, maybe I would have. See? Helmets save lives. Or sometimes end them.
