-Quite so. Humans are much more than an assortment of genetic material.
Cultural heritage and social convention are often more important to an
individual's well-being than genes per se. For instance, the obvious
superiority and rightness of infant breastfeeding is ignored or
suppressed in over 60% of N. American mothers, mostly with the help
of the fake-milk industry and the bizarre cultural sexualization of the
female breast.

-I mentioned to my late granny -- in my youthful naivete -- that old
people performed a vital function in passing on culture, wisdom
bla bla et cetera . She cited examples of burdensome, silly or
destructive oldsters who were better off not influencing younger
generations or being a drain on family resources. Down in flames!

Unlike fine wine, older in humans is not necessarily better or valuable.
