The conclusion reached by the researchers is the same one you’re probably already thinking—the same one that a lot of you probably don’t want to admit, purely for ideological reasons: socialized healthcare. F*ing lies. There is no indication of the researchers explicitly connecting socialised healthcare. They didn't collect data to draw such a conclusion. They collected income+location(+other bits) vs life expectancy, but not healthcare type vs life expectancy. And in reality, I believe Europeans also walk notably more than US-Americans, which might equally well have an impact. And a whole bunch of other things. There might be studies on it. This is not one of them.
