It makes, if cultural expectations lag reality of longer life spans.

I think it does; society thinks 80-year olds are physically less fit than they are in reality, shaping expectations of what 80-year olds should want, and I also think 80-year olds are influenced (even if slightly) by that.

If anything the bias is the other way around. You get to see all the 80 year olds who are fit enough to interact with society. You never see the the ones who are wasting away in their homes, hospices, and hospitals. Being old and needy is an invisibility cloak.

That "slightly" is doing a lot of heavy lifting. At that age people care about society only in the "decent human being" kind of way, not in the "let me please some strangers" kind.

That’s true, but I still think there’s societal pressure on acting old for the elderly.

As a tiny example, if you’re in your 20’s friends and family ask “how’s your job hunt going?”. In your 40’s, they ask “how’s work?”. In your 60s they ask “are you still working?”, even if you’re fit as a fiddle, and even though pension age creeps towards 70 in many countries.

The expectation, basically, is that you work till your mid sixties, enjoy retirement for ten years or so, grow old, and die.

That’s statistically true, but there are outliers. I think that expectation makes some of the outliers at the healthy end reach that final stage slightly earlier than needed.
