Old age

A book I recommend is "In the Company of Strangers" by Mary Meigs. It's a companion to the "semi-documentary" movie "Strangers in Good Company", which I also recommend. Seven old women, and one young one, played themselves in a fictional situation. Both the movie and the book are meditations on old age. I've been looking for something realistic on the subject, and the movie was the first thing I found. Amazon has both. Netflix has the movie.
