Ok, @Jack Swilling and I have found a common interest — enhancing health through diet and exercise (and better living, in general, which involves mental health issues) — in not only living longer but living longer HEALTHIER, which translates into what I call functional longevity. What good does it do anyone to live longer if they are in such poor health you spend all your time with doctors and home health care workers??

To that end, Jack is MUCH better read than I am…
