answer:How old are you HC? I know it was recently decided that it is not polite to ask that of a woman, but nothing was said about a man. Why do you think you only have 15 more years left? I am 66 and for some reason I have in my head that I will live to be 93 and die in my sleep. If that comes to pass and I am healthy, lucid and mobile until then, it will have been a good run for me. If I am not healthy, lucid and mobile then I don’t, at this point, think I would want to live that long. Conversely I would go longer as long as those 3 requirements are met.
