[] Other validated BZs have been found so far in Okinawa (Japan), on the Nicoya peninsula (Costa Rica) and on the island of Ikaria (Greece)...The extreme longevity area identified in Sardinia and named as Blue Zone (BZ) includes a group of 14 villages in Barbagia and Ogliastra, covering the highest mountain area of Sardinia.4...Starting from 2005, in cooperation with D. Buettner, a journalist writing for National Geographic, the BZ concept was extended to other relevant regions of the earth (Buettner 2012). Exceptional longevity at population level has been identified and validated so far in three other settings: the island of Okinawa in Japan, the peninsula of Nicoya in Costa Rica and the island of Ikaria in Greece (Figures 3)..."
