In my life, I have been - in no special order - a sheet metal and construction worker, a college drop-out, undergraduate, graduate and professor, house painter, artist, architectural draftsman, shortstop, college tennis coach, dance teacher, expatriate, welfare recipient, son, brother, father and grandfather. The explanation for this diversity may be simple: DNA testing reveals a kinship with both Tolstoy and Jimmy Buffet and that I am 2.7 per cent Neanderthal.
