You have probably heard the story about Sardinia and the villagers who seem to live forever.
The island's eastern mountains have been studied for decades. What is new is a quiet corner that was not supposed to be on that list.
A demographic analysis published in October 2026 in Frontiers in Aging looked at an average 2,266 residents of Bolotana, a village in central Sardinia, from 2021 to 2025.
The work was led by researchers at the University of Sassari with US collaborators.

Among women aged 70 and older, the chance of reaching 100 came out at 13.83 percent. The national figure for Italian women is 3.54 percent. That is more than a threefold gap.
The gap holds against the rest of the island too. In Sardinia overall and in the surrounding Nuoro province, women at the same age have only about a 4 in 100 chance of making it to 100.
Women in Bolotana who reach 70 have close to 21 more years of life expectancy on average. That is more than two years above the figure for Sardinia as a whole.
The pattern was almost entirely female. Men aged 70 in the village had just under a 5 percent chance of reaching 100. Higher than the Italian average, but nothing like the figure for the women.

The village was not supposed to be on the longevity map
A blue zone is a region with an unusually high share of people living into their late 90s and beyond.
Sardinia's recognized blue zone sits roughly 110 kilometers away, in the island's inland mountains. Centenarian shepherds there have been studied for years. Bolotana was never part of that cluster.
The researchers describe what they found as an unusual, predominantly female pattern of late-life survival. They write that the figures support treating Bolotana as a candidate blue zone, with further research.
What researchers can and cannot explain yet
The study is purely demographic. It counted who lived and who died among the village's older residents, with 149 deaths recorded in the group aged 70 and over. It did not measure diet, blood work, genes or daily habits.

That matters, because the usual explanations for Sardinian longevity are familiar but unconfirmed in this analysis. The authors list several possibilities.
These include genetic background, diet, physical activity, family support, social cohesion, lifelong residence in the same place, and access to care. None were tested directly in this study.
In Sardinia's original blue zone, male survival has historically been relatively favorable too, not just female. Bolotana looks different. Here, the advantage sits almost entirely with the women.
The next step, the authors write, is individual-level research on Bolotana's older women. That means measuring what they eat, how they move and who they live with day to day.
