Bad air = heart attack risk in young adults

Living with the fear of bad air? If you're in a heavily-industrialized city in the U.S. or anywhere, you probably have the term "smog" stamped on your forehead. It's pretty well-known that too much smog inhalation is, umm, not really good for health.

Even if you are a young, healthy adult, bad air quality can trigger adverse health complications, according to a new respiratory study of of Taiwan (of all places). If you've ever seen Taipei, you'll know smog all too well.

The issue here is that these adverse conditions involve possible cardiovascular problems -- even in these young adults. We're not talking about the elderly or toddlers with overexposed or underdeveloped respiratory systems, but completely healthy people. If one were to do a chemical analysis of smog in many cities, I'd be afraid to look at the results. You?
