The 30 “Notes on Living Longer” are selected from the first half of my book You’re Old. I have broken out each item and added commentary and reflections that came to me following the publication of the book. While the components that make up the acronym G.R.A.C.E. provide the framework for what I have identified as the secrets of living a happier, healthier, longer life, the commentary in “Notes on Living Longer” elaborates further on their meaning.
