Sometimes it just feels so good to be arbitrary, and it doesn't really matter how young or old you are. Of course I'm speaking from the woman's point of view after reading today's column by Donald Murray in the Boston Globe. I started reading his column when it was called 'Over 60', but now that he and his wife are well beyond that, it's been renamed to 'Now and Then'. Though his commentary often provides insightful views of aging, today's article delivers a universal, any age scenario. When this arbitrariness hits me, I hope I can say, 'I'm having one of my salad days', trust that it will be understood, and then we can get on with other things.
