This is the conclusion I reached too in a different context.
I see you’re on feddit.uk, so you might appreciate my experience. Probably TMI so feel free to ignore :) I moved to London from South Africa in my early twenties. South Africans are much friendlier and more open than the Brits, and I was raised to be helpful and kind to strangers, except I wasn’t used to the impact of public transport exposing me to so many strangers, or the difference in how people (mostly men) would interpret my behaviour. I had a large number of bad experiences, the worst one being a man following me off the bus one night, expecting to be invited into my home.
Anyway, 6 months after moving there I realised I was walking with my head down, unsmiling, avoiding all eye contact, and not allowing any conversation with strangers. I was miserable, so I made a conscious choice to be friendlier again but to learn to set clearer personal boundaries. It is much harder to look someone in the eye, recognise them as a person, and then say no in a kind but clear way. I’m still not perfect at it and have undoubtedly given away more money than I should have but I’m much happier with who I am.
A woman aged 40 today at least, potentially a woman aged 60 today.
Basis for 40:
The oldest people currently alive are all women around 115 years old, so if nothing changes, that would imply a women aged 40 today will be 115 in 2100.
Basis for 60:
Very old ages are tricky because so far, although we have dramatically increased the average lifespan, 120 has proven to be a hard barrier. We have a lot more people living to 116-118 years old, but as far as I know, only 1 person has been verified to live past 120.
However, just consider the tremendous leaps in medical technology between 1925 and 2000, and then the exponentially increasing nature of information technology. Longevity increases have slowed but there is a tremendous amount of research around it, so statistically it is highly likely that the next jump in longevity will take place in the next 75 years.
There was a presentation at an actuarial conference around 10 years ago, where the estimate was that the first person to reach 150 was already 50 years old. That would imply they would be around 60 today, and 135 in 2100.
