Maybe this has already occurred to everybody else, but the statistic is new to me. From Nicholas Kristof in the New York Times:

Opponents of reform assert that the wretched statistics in the United States are simply a consequence of unhealthy lifestyles and a diverse population with pockets of poverty. It’s true that America suffers more from obesity than other countries. But McKinsey found that over all, the disease burden in Europe is higher than in the United States, probably because Americans smoke less and because the American population is younger.

Moreover, there is one American health statistic that is strikingly above average: life expectancy for Americans who have already reached the age of 65. At that point, they can expect to live longer than the average in industrialized countries. That’s because Americans above age 65 actually have universal health care coverage: Medicare. Suddenly, a diverse population with pockets of poverty is no longer such a drawback.
