Walk along the coast of Oguriastra, Sardinia. Sardinia is an Italian island with crystal clear water and pink hillside flowers, where you can see families eating fresh fish, people working on the land, and older couples strolling the hills.
You may also see an extraordinary number of 100 people. This region of Italy is one of the three Sardinian provinces that make up the blue zone. This is a small number of regions in the world with a disproportionately large number of very elderly people. These areas have been highly praised by researchers who want to clarify genetics.
