People think healthy living involves rare treasures and dark secrets—the exotic plant from a Tibetan meadow, the secret advice from a sage in a remote village—or years of intense study and practice. Actually, the truth is hidden in plain sight, and it's pretty simple (though seldom easy). That's why The Merck Manual of Health requires only one sheet of paper.
Diet and Nutrition
Vitamins and Supplements
Exercise and Sleep
Injuries and General Safety
If you do all of these things but think you need something more, take the time, effort, and money you'd spend looking for a better supplement, diet, or exercise and instead read a book to a child or help those in your community who are in need.
Yours in Good Health,
