While smoking, excessive drinking, stress, obesity and lack of exercise are lifestyle choices that can shorten your life, thanks to modern medicine you nevertheless have a really good chance to survive (albeit not feeling great) well into your 80s.
But if modern medicine didn't exist, what are the factors that could see you into a healthy old age?
National Geographic writer and explorer, Dan Buettner, who studies the world's longest-lived peoples, travelled the world in search of an answer.
What he found is that the longest-living societies all share certain social, environmental and psychological factors. He calls the areas where these people live “Blue Zones”.

According to the Beuttner in the New York Times they have the following in common:
· An environment that encourages a healthy diet and plenty of exercise
· Healthy relationships with other people and good psychological health
· Looking after gardens
· Having a spirit of cooperation
· Easily accessible public health
· Being valued as seniors by their families and communities
These are the areas in the world where people live the longest, and why:
1. Okinawa, JapanOkinawa has the world’s highest percentage of centenarians, and boasts both the highest life expectancy and the highest health expectancy on earth.

2. Sardinia, Italy
Sardinia is an island off the coast of Italy where especially the men have a very high life expectancy. Most of them are farmers or shepherds.
Their secrets: Sardinians have a history of longevity, but they also follow the healthy Mediterranean diet with a lot of goats’ milk and cheese. They get a lot of exercise, but also have a lot of free time. They are very positive and have a great sense of humour.
3. Loma Linda, California
