Keep posting, Ralph. Your perils of wisdom are enthralling, at least, to me! You're showing us by means of your posts, all the side effects of having partaken of a public education in America's Deep South. By the way, you might be fortunate enough to bump into Professor Turnoi there. He has just left China for a much better position in a southern state famous for its 'gator population! Chin up my man, irrespective of how others on here respond to your posts! Not all of the responses eill be positive!
