I just noticed a mildly interesting numeric thing: I was born in ’61 and I turned 61 this year. This is a thing that only happens once in a lifetime, and for some folks never. The later in the century you were born, the less likely it is that you will live to see this event. For every year that passes the date of the event advances two years (all my fellow ’61s are turning 61 this year, but the ’60s turned 60 two years ago and the ’62s turn 62 in two years) and the event occurs only in even-numbered years. As I said, mildly interesting.
