We're just Fat Slobs

Here's an interesting take on health care: what if US health care is the best in the world and is only more expensive and Americans are sicker because we're basically a nation of fat slobs. The article points out that Americans for many years smoked more than other nations and we're more obese. So, under any system of health care, we would have massive problems. Perhaps given the lifestyle choices of Americans, our system is performing better than any other would. So, if the problem isn't the health care system but our bad diet and lack of exercise, don't we risk screwing things up for no reason?
