The next question is, what are the healthy lifestyle choices that can help you live a long life? The best way to figure this out is perhaps to do a reverse research. To see the lifestyle of those who are already living for such a long time. In the early 2000s, Dan Buettner, an explorer and author, was working for National Geographic. He decided to study such places in the world where people live the longest.
In 2003, he collaborated with anthropologists, historians, dietitians, and geneticists to complete this mission. They used population data to locate such areas in the world where the most number people of ages 100 and above are found. These people are called Centenarians because they have lived a century. Around this time, some other people were also researching the same thing.
Like this research paper that was published in the Journal of Experimental Gerontology. Here, they identified that in the Sardinia region of Italy, the highest concentration of male centenarians is found. Those who are 100 years or above.
The Italian villages with the highest concentration of these people, were marked by blue circles on the map. These places were referred to as the Blue Zone.
