'''Blue zones researchers did not rely on data crunching from afar; the research project’s goal was to actually go to these supposed longevity hotspots and validate or invalidate claims of exceptional longevity. It wasn’t based on datasets from afar. The author of the pre-print didn’t do his research, unfortunately. A team of researchers, demographers, and scientists visited each region to validate age. We checked birth certificates and cross-referenced with church baptism records or other available local records in all the international blue zones regions''
Edit 2: Incidentally John Tinniswood, currently the oldest man in the world at 112 seems to have lived a life which would leave a long verifiable paper trail. He's from Liverpool not some remote Chinese village. It's odd Saul Newman dismisses him as the result of someone writing his age down wrong at some point.Blue zones areas are not those with the most supercentenarians as the pre-print describes. The blue zones areas are places with the highest healthy life expectancy, where people reach their 90s with low rates of chronic disease, and where there is a high probability to reach 100. The blue zones criteria are clearly laid out.''
