Kimura’s case sparks skepticism about longevity records. Oxford researcher Saul Justin Newman, winner of the 2024 Ig Nobel Prize, argues systemic issues—not isolated errors—plague studies of extreme aging. His book *Morbid* details how birth certificate allergies and record-keeping flaws may explain why many supercentenarians’ claims are dubious.

Newman highlights Christian Mortensen, a record-holder who smoked for decades, and Juan Vicente Pérez, a man with no official documents until age 50. The Guinness Book of Records retracted Carrie White’s status after uncovering a clerical error. These examples suggest longevity science is entangled with fraudulent age claims and demographic distortions, skewing public policy and research priorities.

The problem extends to blue zones—regions touted for exceptional longevity. Newman critiques Dan Buettner’s commercialized model, which included Loma Linda (added for U.S. representation) and Okinawa, where residents consume KFC and smoke. He argues low-income areas like Tower Hamlets or France’s Guadeloupe appear overrepresented in longevity data due to missing or faked records. This challenges the validity of public health initiatives tied to blue zone lifestyles.

The 2010 Japanese census revealed 80% of centenarians were deceased or missing, exposing pension fraud. Greece’s 2011 census found 2% of its population engaged in age deception. Puerto Rico’s 2010 birth certificate purge underscores identity theft risks. If Newman’s theory holds, longevity research and policy decisions—from Social Security to medical funding—rest on shaky foundations.
