Sometimes I will start rereading a book accidentally. Then I remember more and more as I read on. Unfortunately the more I remember, the less I enjoy rereading. Same with TV and movies.
I do like series books because of the familiarity with the characters so I get a similar pleasure perhaps from that.
Luckily for me there are a lot of books but perhaps it will be a benefit of advancing senility that I can reread all of the Nero Wolf books again and many others
