Thanks for the info tb! I looked it up, and if we consider yesterday's 24hr average of >500, inhaling that for a day is about 75% of a cigarette. Ok so I won't DIE die anytime soon... I just get a kick out of the collective freak-out yesterday. LOL

That said I wouldn't want to be raising a kid in this environment. I don't have an air filter, but if I had a kid I'd have several plus make the kid go out in a bubble suit!! Heh.
