Some anomalies/questions which are not necessarily important, but do puzzle me or where I find existing explanations to be unsatisfying.
Jeanne Calment holds the verified record for human longevity at ~122.5 years at her death over 22 years ago: Calment is history’s first & only 122 year old; and also the first & only 121 year old; and also the first & only 120 year old. No challenging centenarian has come close to her record, and arithmetically, they will not for years to come: she will have held the record for a minimum of 3 decades, despite countless countervailing factors. Some statistical simulations suggest that Calment-like record gaps are not expected from the distribution of human life expectancies, and as time passes, her record becomes increasingly anomalous.
This truly remarkable longevity raises the question of whether Calment’s longevity is due to the same factors as all other centenarians: did she benefit from some unique factor like genetic mutations, or, as accused in late 2018 of being, is she, in fact, merely a fraud which has fooled previous verification?
