Today, women run from task to task trying to do more and be more than at any other time in history. At first, we push ourselves, relying on an adrenaline rush, the boost of cortisol, and maybe some extra caffeine to address today’s crisis (real or perceived). Initially, we recover quickly from the additional demands that we have placed on our bodies and our minds. But when we call upon these stress hormones to boost us to heroic heights time and again, our bodies can do nothing else but operate in fight-or-flight mode 24/7. This sets the stage for all kinds of medical problems—and a very unhappy life.
