My wife used to be a home health nurse. One of her patients a couple years back was damn near dead from smoking and had bad emphysema (sp?), well he decides to smoke w his oxygen on and somehow it catches fire and burned the crap out of his face, inside his mouth and lungs. Dude survives and his face looked like Freddy Kruger, got skin falling off and green oozing stuff going on. Would you believe the first time she goes to visit after he comes home from the hospital he has the oxygen on, and is smoking again. That's just plain stupidity. As if God hadn't already said hey dummy here's some emphysema to get you to stop. He didn't get the point, blew his face up and still did it again. Unreal.
