“Why does everyone seem to have a problem with the exceptions who live past 120, but not with the vast majority who don’t reach 120? Isn’t that equally problematic according to the 120 yr “myth”.”
No; the idea of “until 120” is that no one can live past 120 and not that everyone HAS to live until 120. 70 is considered the “normal” or “average” (not sure which word is more accurate) lifespan.
