Singapore is the world's sixth Blue Zone, according to Dan Buettner, a journalist who popularized the term. In the Netflix series "Live to 100," Buettner shows how the country is designed to encourage its residents to live healthier. Policies on housing, transportation, and hawker centers come together to create what he calls a "Blue Zone 2.0." The original five Blue Zone regions include Okinawa in Japan, Ikaria in Greece, Sardinia in Italy, Nicoya in Costa Rica, as well as Loma Linda in California. "You share tables and you're interacting with the stall user, interacting with the person next to you," Buettner told Fortune.
