Uncovering the key habits and traits of people who live exceptionally long, healthy lives.
What makes exceptional longevity possible? Researchers decided to find out and ended up focusing on specific villages with the highest number of elderly men, which they called “Blue Zones”.
Interest grew when Dan Buettner and National Geographic extended the project. Buettner and a team of researchers identiﬁed four other areas of the world that stood out for longevity and low levels of chronic diseases, such as heart disease and dementia. They came up with five areas of the world that have become known as the Blue Zones, namely:
- the Japanese prefecture of Okinawa;
- the Greek island Ikaria;
- the Nicoya Peninsula in Costa Rica;
- Seventh Day Adventists living in Loma Linda, California; and
- the Barbagia region of Sardinia.
