One of the things I hope to avoid through active transportation is heart disease. However there are lots of people out there who for whatever reason (inactivity, genetic predisposition) will suffer sudden cardiac arrest.
Like many people, I had to study CPR in 10th grade gym class, with the scary "recussa- Annie" dummies, but I 'm not sure I'd really feel comfortable trying it on a real person. So I was interested to learn that there's a new "modern" approach to CPR called CCR (continuous chest compression) that's targeted more to laypeople than trained responders.
I'm going to pass this along- take five minutes, learn a valid reason to get "Staying Alive" stuck in your head, and if you ever need to, you can be a Good Samaritan without having to recall those days in the high school gym.
