Italy – 82.84

Italians are a bit of an enigma – despite all the smoking, carbs, and the lower incomes than other countries on this list, Italy has the third highest life expectancy in the world. Glossing over the previously-discussed Mediterranean diet and temperate climate’s positive effects, Italy has long-been a more cohesive society than many others on this list. Lower levels of social turmoil and inequality seem to play an important role in Italians’ better health.
