Younger Next Year - Recap

I'm reading Younger Next Year as I wait for my car. I'm on page 29. This paragraph says it all:

"A lot of people unconsciously assume they they will get-old-and-die:  one phrase, almost one word, and certainly one seamless concept. That when they get old and infirm, they will die soon after, so a deteriorating quality of life does not matter. That is a deeply mistaken idea and a dangerous premise for planning your life. In fact, you will probably get-old-and-live. You can get decrepit, if you like, but you are not likely to die; you are likely to live like that for a long, long time. Most Americans today will live into their mid-eighties, whether they are in great shape or shuffling around on walkers. And that number is rising over time, too, so you may live well into your nineties, whether you like it or not. Which is a good reason to make the last third of your life terrific-and not a dreary panoply of obesity, sore joints and apathy. "Normal aging" is intolerable and avoidable. You can skip most of it and grow old, not just gracefully, but with real joy."  Dr. Henry S. Lodge, M.D.
