TAKE A CPR COURSE.
It could save a life.
And if a lot of people are aware of how to do it then it could also save yours God forbid you need it.
Its soooooo worth it and more than likely a necessity for someone waiting on an ambulance here. Reminds me of an old rap song, "911 is a joke".
So when people ask what they need in preparation. I will add to the list-"cpr classes.child and adult". Nothing serious has happened that I am aware of BUT I regret the fact that I didnt do it at home and pray that I dont need it or need to administer it. Observations say it is necessary and there is no price to put on a life.Even if you've never met the person.
