That was on the evening news the other day, and I must say, I was surprised. I didn't know it was the 3rd year in a row until I read the article you posted. The news report said Los Angeles was #22 on the fittest list, which I found surprising as well. They attributed the problem in Houston to the fact that it also has the worst air quality in the nation, but if that were true, than L.A. shouldn't have been on the fittest list at all. Granted, the air quality in L.A. has improved dramatically, but it's still pretty bad. It's also a very spread out city, which makes me think the humidity must have something to do with it. Then again, it's pretty humid in Hawaii, and they were the fittest. Must be the food.
Now I'm hungry.
Take care,
