It’s interesting to note that any recorded cases of someone living past 120 are all female as far as I know.
It seems that even if there is any truth to the “120 years myth”, it only applies to men.
That may explain why some people say ???? for women instead of ???”?
I still don’t get why we say “until 120” for anyone though. As far as I know, it doesn’t say anywhere that it’s impossible to live past 120 (even if it hasn’t happened since Moshe Rabeinu), so why put a limit on someone’s lifespan?
