Sardinia is home to the oldest men in the world

The blue zone is a name born from the discovery by researchers noting an extraordinary longevity in Sardinia. In the year 2000, the academic Gianni Pes and the demographer Michel Poulain identified in the province of Nuoro the highest concentration in the world of centenarian men. This male population, often composed of former shepherds, displays there a life expectancy equivalent to that of women, with 30.9 centenarians per 100,000 inhabitants.
