If so, then it's really hard to explain how female humans manage to live 40 years past their reproductive age.

Animals also live significantly longer in zoos.
Average age of death has gone up, due to asprin, antubiitics, vaccines, improved hygene, and so on.
I don't buy the wear and tear side of thibgs, and zoo animals, pets have vaccines, health care, medicine, and checkups too.
In warm regions, perhaps HVAC / having at least rudimentary shade is equally important.
And houses for shelter just as long.
Unless you think people lived without houses in the 1800s, and heat, it's modern medicine that's changed, dramatically, the outcome here.
Ans there are plenty of moderate climates that had no better life expectancy than colder ones.
We had a lot of shaping by selection of existing traits but not that much long term evolution. We're essentially "running on the same hardware" as these pre-house Homo Sapiens.
What allowed prehistorical Homo Sapiens to live for 50 years now lets us do so for 80.
You need to look at life expectancy rates for the last 200 years. The big change is in the 1900s.
Not when we first built warm, heated houses, thousands of years ago.
You want either modern medicine and sanitation, or low population density. The latter is very hard to combine with low wear and tear. So it's really both medicine and comfort.
Humans and many apes probably had similar lifespans in the wild, but humans have this huge post-reproductive lifespan in safe environments that other apes don't.
Human males don't, though. They're often reproductively capable at 60.
