couch baboons?

What you eat is important, but exercise may be more important for being at risk for diabetes and obesity.

Two wild baboon groups were watched.  One had to work for their food, the other had an abundant food source.   There is always a risk extrapolating to humans, but there is a lack of activity in countries like the US, where 61% of adults were overweight or obese ten years ago ...  Even more troubling is the increase in obesity among children in America.
