Where? Bermuda

Average Life Expectancy: 81.4 years
Official Language: English

This area is best known for its pink-sand beaches, but it also has one of the highest life expectancies in the world. There is a severe gender gap, though: Where women live to be 84.9 years of age on average, men only make it to about 77.3 years.

This is mainly due to various health issues that affect men, like that 70 percent of Bermudian women are overweight, compared to 79 percent of Bermudian men.

In general, obesity is a significant problem in Bermuda, which suffers the highest obesity rates of all Organisation for Economic Co-operation and Development countries.

About 13% of the population suffers from diabetes, and the diabetes-related lower-extremity amputation rate is nearly double the average of OECD countries.

So why does Bermuda still have such a high overall life expectancy? A healthy love for the outdoors and a strong sense of community undoubtedly play a role. Plus, only 10% of Bermudians are smokers, one of the lowest rates in the OECD.
