I agree dorro. I am 85 and slowly losing my faculties. I love to read and to do other things, like using this computer, (which use my eyes) and unfortunately for me I have macular degeneration, age related, which means I will eventualy not be able to do these things although still able to function. I also have to wear a hearing aid which definitely helps. I think I am fortunate to have lived in these centuries so that at least I have help to see and to hear. It could be worse - a lot worse - to be born in previous centuries when there was nothing available to help.
