Oh, the ravages of aging! Was watching a little tennis, today (I try to watch Wimbledon when I have a little time to myself), and saw a face I recognized at court side. It took me fully 5 seconds to realize who it was. How awful is aging, if it makes one unable to tell Ann Jones from Bjorn Borg!
Incidentally, the same was always true of Golda Meir and Lyndon Johnson, in their middle aged years. It was impossible to tell those two apart, for anybody but their very nearest and dearest.
