"Can you imagine us years from today
Sharing a park bench quietly?
How terribly strange to be seventy."
I wasn't yet twenty when Simon and Garfunkel released the album "Bookends" and I first heard those lyrics from "Old Friends" that would haunt me all my life. Fifty years on, I don't find it terribly strange to be seventy. What I find terribly strange is to reflect on the fact that there are no songs about what it feels like to be 120. The milestones in my life are piling up behind me. The road ahead is becoming less congested. The horizon is ever closer. Melancholy fills me. That is what I find to be terribly strange.
