For those readers who have seen their 53rd birthday, it was probably not a remarkable occasion. Perhaps it passed by without notice, and why should it? It isn’t regarded as a major milestone like 21, 50, 60 or 75.  What good is 53? It is often overlooked because we rarely run into it. We put 52 cards in a deck, but 53? We can’t deal with that.

Earth Day probably felt that way this year as Saturday, April 22, went by with fewer people marking its 53rd birthday than in previous years. Collectively, the gifts in its honor seem smaller, less meaningful.
