"A few years ago, however, the health-care economists Robert Ohsfeldt and John Schneider recalculated the numbers after controlling for deaths from homicides and traffic accidents. Because these things tend to strike very young people, they can have an outsize impact on mortality statistics. Those deaths reflect America’s crime policy and its driving habits more than the effectiveness of its health-care system. And if you remove them from the picture, say Ohsfeldt and Schneider, America jumps to the top of the life-expectancy tables."
