A thought. Coffee is a (relatively mild) stimulant. I wonder how much of coffee's benefits can be attributed directly to that, as opposed to whatever else caffeine may do? Given that these studies tend to be done in first-world countries, where obesity and people being underactive are a problem... Overgeneralizing of course. If nothing else, sitting still for long periods of time is known to be bad for you, and caffeine helps people avoid that.
