Residents of the original blue zones areas make healthy choices because those choices are easy—even unavoidable—in their surroundings. That’s why Blue Zones Project focuses on influencing the life radius, the area close to home in which people spend 90 percent of their lives. In Blue Zones community transformations, we optimize the built environment, municipal policies and ordinances, restaurants, schools, grocery stores, faith-based organizations, and workplaces, social networks, habitat, and inner selves. Our work is rooted in lessons learned from the world’s longest-lived cultures. We translated these lessons into environmental changes that strengthen social ties, reshape places, and sharpen policies to support healthy choices.
