Hmmm. It has been almost 13 months since I posted here. Too long. It is a curious fact that fifteen or so years ago, in my early fifties, i could not wait to retire. Now, in my late sixties, I have no desire at all to retire. Somehow, the work I am doing has become fun again, as it was in the 1960's and 1970's. I am not sure why, since the working conditions are no better. Our students are somewhat better than they were around 1990, on average, but I am not inclined to consider that too big a factor.
