I discovered something a couple of years ago: Almost all culture, old or new, is designed for consumption by people under 40. People between 40 and Ω (an indeterminate number defined as “really, just way too old”), are primarily employed as meaning-makers for the under-40 set. This is because they are mostly good for nothing else, and on average not valuable enough themselves for society to invest meaning in.
The only culture designed for people between 40 and Ω is prescription drug ads and unreadably dense literary novels. Between age Ω and ∅, the age at which you die, there is only funerary culture. That second link is to an app for managing your own death called Cake. Why cake? Your guess is as good as mine.
But there’s a plus side. Forty is when immortality begins.
