Live to 100: Secrets of the Blue Zones Season 1

Buettner travels to Okinawa, Japan, where the island's oldest residents still share a serene way of life motivated by a sense of purpose, or ikigai.

From the mountain villages of Sardinia to a sunny suburb of California, Buettner explores what has contributed to these communities' amazing lifespans.

People in two very different Blue Zones — the Greek island Ikaria and Costa Rica's Nicoya Peninsula — thrive thanks to their unique diets and traditions.

Buettner visits Singapore, then shares his discoveries in the United States to find out if we can create new Blue Zones in a rapidly changing world.
