The article presents a lot of correlations, but it'd be good to see a little more investigation into which are actually explanatory.
Fitness is associated both with income per capita and the share of adults holding a college degree, but income is strongly related to education already. If you control for education, does increased wealth still correlate with fitness? From reading TFA, it doesn't look like the study author tried to figure that out.
