If the threat of the next big earthquake doesn't scare you away from L.A. the constant threat of toxic air might. It doesn't take a genius to know that jogging with traffic at rush hour is not a good idea, but most of us (geniuses included) ignore the quality of the air until its noticeably bad. Unfortunately, here in LA you kind of grow accustomed to the brown blanket of air above you and only feel its threat when it becomes apocalyptically opaque.
Don't look to the locals for commiseration, they'll tell you to get a grip because at least the air isn't what it used to be. Well, the American Lung Association State of the Air report will tell you that, better or not, LA continues to be one of the most polluted cities in the nation. Yeah, we're all aware of that fact but check out the graphic below and note where the cutoff is for a grade of F.

I'm thinking of wearing a face mask the next time I go outside. Hopefully your city isn't so toxic, check out how it ranks here. And if you're still thinking about moving to LA please consider buying an electric car first, the city can't handle one more ounce of emissions.
