For over a decade, author Dan Buettner dedicated his efforts to uncovering global longevity hotspots. Collaborating with the National Geographic Society, Buettner embarked on a quest to pinpoint regions characterized not only by a significant population of centenarians but also by communities of individuals who had aged gracefully without succumbing to health issues such as heart disease, obesity, cancer, or diabetes. The results of his extensive research, as well as practical lifestyle recommendations inspired by these remarkable cultures, are detailed in his book, "The Blue Zones Secrets for Prolonging Life: Insights from the World's Healthiest Regions."
