I do not think age has anything to do with it, it all depends on what your interests are and where in your area you can access them
As a young woman I quickly tired of social events of the kind you mention. I much preferred to get involved with other people through pursuing things that interested me: the sailing club, politics, music when I was young, various children focussed groups when my children were small and since then archaeology, friends on a one to one basis, environmental and heritage causes.
I do Tai Chi and when we are doing our class I hear the music from the Tea Dance group in the adjacent hall.
Yes, where you live will affect what is available in your area, that was why my parents, when they retired, fully researched any area they were considering moving to check that it had organisations that offered activities that interested them. My mother died in her late 80s, my father in his early 90s and both were leading active social lives to the end.
We are all different and even when we are old there is enormous divergence in what we do with our time - as there was when we were young
