Mr Phil may I offer you a cyber hand shake on your obviously great level of civility. I suppose I can never suppress the tendency to teach (and learn). Even being old, with aches and pains in places I never knew existed, learning something new is quite precious to me. I hope I have express with enough frequency my profound thanks to many of you who have shared information that I absorbed with rapidity that astonished me. Maybe I should say it another way: I have researched, and purchased items, so many topics, so many items because of erudite observations, comments, and reviews on this site I lost track long ago.
I just completed a headache producing fast track learning splurge about the ebola virus. Three hours worth. Yes I am "hooked on learning". I should have known when I became disabled that I would never turn into a couch potato. "Retirement" to me is having so much time I learn faster by making more mistakes. :)
