You take off hours from work to go in for your annual physical exam, and then sit on the hard, paper-covered table while answering the same questions you answered at last year’s physical. After a few minutes of gentle poking and prodding, your doctor tells you you’re in good shape. For years, his cholesterol panel had been looking increasingly abnormal, but his doctor had shrugged it off as not yet urgent enough to act on. Buried in them was a letter after his 2014 annual physical: Your cholesterol panel is abnormal. The recommendation would be to eat healthy, exercise, and sleep, which are all things you are already great at.
