Earlier, I commented on a glorious pleasure of age: the afternoon nap with snoring. I have them now on an almost daily basis. But I have always envied the ability of an old professor to nod off during a lecture given by someone else. He or she may give an introduction, especially if it is a visitor, and then promptly fall asleep, with snores, for the full stretch of the lecture. At it’s close, he or she is then able to ask a question and end with words of thanks. So that is my next aim: the lecture nap. I have a few conferences coming up, so intend to use them for some serious practice.
