My husband ran in a 4 mile race on new years eve, and at about the 3.5 mile mark he ran buy a guy that had a heart attack, and there was a police man with a portable defibulator (sp?) shocking him. He kept running as he did not want to get in the way, but what an interesting experience.
We later read that the guy is doing well, thank God!
My husband finished the 4 mile race in about 45 minutes which is not that great, but he is not in as good of shape as he would like as it is hard to work out as much in the winter.
