ABSTRACT

As the first speaker, it falls to my lot to welcome Sir Alec into the Club of Nonagenarians. Some of you may protest that he has become merely an octogenarian. I cling to the view that he is completing his eighth and entering into his ninth decade. Join the Club, Alec. Eighty is a good round number; 81, coming up, is a square number. If you regret leaving 79 which was a prime number, take comfort from the fact that when you reach 83 you will be in your prime again.
