National Geographic has published a coffee-table-sized paperback, “Blue Zones: The Science of Living Longer”, by Dab Buettner, 112 pages, gloss, heavily illustrated (professional photographs).
The book comprises three parts: Discovering the Blue Zones, Build Your Own Blue Zone, and Cooking in Blue Zones.
The Blue Zones include Nicoya, Costa Rica, Ikaria, Greece; Okinawa, Japan, Sardinia, Italy; Loma Linda, California, where the Seventh Day Adventist denomination is active.
CNN’s Sanjay Gupta has covered the zones before.
