*cue in music by The Fray* No, I’m not being dramatic. I did learn how to save a life…theoretically, anyway. That’s because I took a class on CPR, AED, and first aid for adults. You probably know what CPR is — cardiopulmonary resuscitation, or revival techniques like chest compressions and what we often call “mouth to mouth” — but if you’re anything like me, you’re might be going “huh?” about AED. It stands for “automated external defibrillator,” that handy device that “shocks” a failing or irregular heart into proper rhythm. But more about that later. I’d never planned on attending such a class, but when my brother invited me to join him and his team, I figured I might as well give it a shot. You never know when it’ll come in handy, right? They hired a team of licensed medics, and we all gathered bright and early on a Saturday morning for a full day of lectures and exercises.
