While I am a a regular contributor to OpEdNews.com on history and politics, for this column I am taking a very different focus. As a career Professor of Preventive Medicine I have published a number of books and numerous columns/articles on various aspects of personal health and wellness. And so, in this first column for the New Year, 2024, I am sharing with you "Dr. J.'s 20 Guides for Healthy Living," developed over time.
