Nature must provide some sort of tranquilizer that kicks in as we approach the end of life, allowing us to accept the unacceptable. Otherwise why am I not more alarmed that I can’t remember the titles of movies or the authors of books or the names of public figures that have been familiar to me for years? Usually they come back easily when I stop searching for them, but at other times I have to find the book or consult the Internet. I believe many people in my age group experience this.
