There are certain things that make me feel my age. The very idea of running is one of them; I fear that these knees have probably taken their last long stride. Another is the thought that my oldest daughter will soon turn forty. How dare she? A recent third: my 50th high school reunion. It was horrible and it was wonderful. Amid the surf and turf dinner and the Motown covers, I was faced with the reality that these old-timers were my classmates, and that I was one of them. Denial was impossible. I found myself swimming in a genial acceptance, laughing and marveling over where life has brought each of us. I didn’t come away with any big life lessons, but I did get a sense, at least for one night, that the world is turning at the same pace for everybody, and that there is no reason not to dance to The Temptations whenever you get the chance.
