The Importance of Environment for Longevity

Longevity is significantly influenced by environmental factors rather than solely by genetics. While only about 20 percent of lifespan is determined by genetic inheritance, the remaining 80 percent is largely shaped by one’s surroundings. Dan Buettner identifies specific regions known as blue zones, where the environment actively promotes health and wellbeing, allowing residents to live longer and healthier lives. These blue zones are characterized by lifestyles that naturally encourage physical activity, strong community ties, and a focus on a plant-based diet.
