Short little snippet of an article at Slate proposing alternate contributing reasons (besides much disucssed corn syrup, super-sizing, car-culture, etc) for America's obessiety problem -- Such as inadequate sleep (interesting), heating and air-conditioning (I'm a bit dubious), smoking cessation (very interesting), and medications (Seems almost obvious; I wonder how much of a factor this actually is? This article in the NYT on Sunday implies it could be a big one)
