Anthropologically, I think that this isn't super far from what has already happened for humans. Grandmothers specifically had a lot of repsonsibilities and importance and I believe that's why they generally live longer than grandfathers.

Instead of being about career development, it's been about specializing in hunter/gatherer stuff while still able bodied.

Iirc that's at least partly due to estrogen & other female hormones. They have I think anti-infection or anti-cancer properties. (Though if your comment was from an evolutionary perspective that would make sense.)
