Switzerland – 82.66

An Alpine paradise, Switzerland boasts high incomes, clean air, and happy people. A major reason why the Swiss live so long? The World Economic Forum’s Human Capital Report in 2013 cites Switzerland as the country which invests the most in its citizens’ health, talent, and education. Combine a well-cared-for population with low crime rates and strong social cohesion and you have the working for one of the longest lifespans in the world.
