Longevity myths are traditions about long-lived people (generally supercentenarians), either as individuals or groups of people, and practices that have been believed to confer longevity, but for which scientific evidence does not support the ages claimed or the reasons for the claims. While literal interpretations of such myths may appear to indicate extraordinarily long lifespans, many scholars believe such figures may be the result of incorrect translation of numbering systems through various languages coupled with the cultural and/or symbolic significance of certain numbers.
