What you’ll learn

Introduce the blue-zone concept and the five regions where people live exceptionally long.Blue zones are longevity hotspots popularized by Dan Buettner: Sardinia, Okinawa, Ikaria, Nicoya, and Loma Linda, each combining whole-food diets with movement, community, and purpose.
Identify the shared lifestyle patterns behind blue-zone longevity and the appropriate caveats.Across all five zones, people eat mostly plant-based diets, move naturally throughout the day, hold a strong sense of purpose, and maintain deep social connections, though longevity science warrants humility about data and single-cause claims.
