Perhaps we should be looking at function levels at 70, 80, 90% of lifespan rather than looking for quantity of life.
Logistically speaking, humans tend to have a lot of disposable income at 60-70% of life expectancy. From the Enlightened Self Interest perspective, extending that zone before functional decline would not only improve society but also be profitable.
Yep, optimize healthspan not necessary lifespan. Best to do both and “rectangularize” survival functions (falling off a cliff). Lots of effort on this now.
