Doctor explains five global areas where people live longest: 'Genetics account for only 25%'

Genetics play a surprisingly small role in how long people live, accounting for only 25% of lifespan, according to Dr. Jorge Tartaglione. He emphasized that individual choices and lifestyle habits determine the remaining 75%, offering a hopeful outlook on extending life.

“

Because only 25% of what you are going to live is written in genetics. Instead, we define 75%.

"The art of living longer and better" involves cultivating faith and a sense of purpose, Tartaglione explained. He pointed to Loma Linda, California, where residents live longer due to their religious beliefs. Similarly, in Costa Rica, an 80-year lifespan is common, attributed to a diet rich in tropical fruits and a relaxed lifestyle.

“

In Loma Linda, California, people live longer because they have faith, they are religious (...) these people have 10 more years of life because they have faith and are religious.

Physical activity and natural diets are also crucial. In Icaria, Greece, residents walk extensively throughout the day, contributing to their longevity. Sardinians in Italy thrive on natural, unprocessed foods, while Okinawans live by the motto "I will have a life goal every day," finding purpose in daily activities like meeting friends or walking their dogs. Many 90-year-olds in Okinawa remain active, dancing and singing.

In Costa Rica, they live more than 80 years because they consume tropical fruits, they are calm.
