As I approach my 88th birthday it's become apparent to me that my eyes and ears among other appurtenances aren't quite what they used to be. The prospect of long flights to wherever in search of whatever are not quite as appealing.
At a certain age it just became apparent to me that this was probably the work that I would have to do.
Human beings who are almost unique in having the ability to learn from the experience of others are also remarkable for their apparent disinclination to do so.
