Not all of the joy, but a lot of it. My dad was born in a village in Bangladesh. Like a real village. They practiced subsistence agriculture and didn’t get electricity until the 1990s. One out of every three children died before age 5. They lacked of everything a typical child-free American would need to consider life tolerable. But believe it or not, most were pretty happy.
The same year, 66% of people reported they were “very happy” with their life. https://www.thedailystar.net/frontpage/bangladesh-tops-list-.... Sure, Bangladeshis aren’t as happy as Americans. But the average Bangladeshi lives an existence that would drive your typical child-free American to suicidal despair. What do they have?
I mean, I think it should be more probable that most people would prefer living longer over not, considering the fact that, at any given moment, most people do prefer to continue living.
That in our society wanting immortality is somehow the "fringe" view (not to mention often depicted as evil) is pretty crazy IMO.
