Walter M. Bortz II, M.D.: Dare to Be 100: Nature, Nurture, or Both?
I am a student of the Serenity Prayer, which teaches, “Change what you can, accept what you must, but know the difference.” I like the idea that most of this option is up to us. Among my life choices, I choose to be active. Age does not disqualify me from this imperative.
