Okay, let's look at those. Loma Linda, California is Seventh Day Adventists: vegetarians. Okinawa has a high wild seafood and seaweed diet. Ikaria is noted for its thermal springs and rugged terrain. Sardinian diet is Mediterranean with wild meats (Over to you, Fred!) and raw milk cheeses. Nicoya: beans and tortilla diet. No earthly reason Singaporeans should reach great ages, esp considering capital punishment. I have only emphasised diet. It's also lifestyle. Exercise to accomplish something, not just running a treadmill mindlessly or rowing a machine to nowhere, using all your muscles in real life. All these places have a sunny disposition. These 95-year olds are still active and not addled. My BIL comes from a village outside Thessaloniki. His mother was still cooking for her extended family, keeping sheep to make feta, picking wild oregano in the hills and tending an enormous tomato patch at 97. She got to meet with four generations!
