According to researcher Saul Justin Newmann, ‘The data on extreme human ageing is rotten from the inside out’. We don’t think so Saul. And either do the demographers who did the bulk of Blue Zones research. 5 of the world’s top demographers have come out and picked Newmann’s pre-print “research” to pieces. (Pre-print meaning this research has never been published; in other words unable to get pass the rigour of peer-reviewed research.)
