I know it is hard to control for culture, but seeing as how mormon men are still American but have a 10 year gap in life expectancy over other American men [1], any analysis on the effects of health care across nations should at least try to control for cultural differences. That singular cultural difference is twice the magnitude of the difference between the OECD and the US. And when you realize that culture could be a far stronger predictor than health care quality/availability, you start wondering how much of that gap is due to us being fatasses.
