My job requires me to take a CPR class every other year, but I end up taking it every year. I think I would know what to do, and I believe remembering wouldn't be a problem but man.........I hate the thought of ever having to do it. I don't think that using my first aid knowledge would both me, but CPR is very scary to me.....especially in an outdoor environment. I think the second worse thing that could ever happen to me would be administering CPR....the first would be having someone administering CPR on me.
