Fat Workers

A recent New York Times article reported on a study linking desk jobs to weight gain. Over the past half century or so, as American workers spent more of their day sitting at a desk, their weight increased. That's the theory.

Clearly, workers are doing much less physical labor than they once did--at least some workers. And there lies the problem with the theory. Hispanic men, who are the most physically active workers according to the CDC, are more likely than the average man to be overweight (78 versus 70 percent).
