alt Hacker NewsYeah, I agree that the "Blue Zone" theory is mostly explained by bad record keeping. Okinawa is one of the poorest areas of Japan, but was deemed a Blue Zone, despite that wealth is nearly always positively correlated with longevity within similar cultures. Low and behold Okinawa had shitty record keeping and tons of incentives for relatives to commit pension fraud.
This is dumb. If you go to any Japanese graveyard in Hawaii (where family graves have prefecture of origin) you will find the preponderance of centenarians are from okinawan families. There is no incentive for pension fraud for someone born in the us (or emigrated to the us in their younger years) and died in the us in the 1980s-> early 20XXs
