A few years ago when I turned 50 and my world was topsy-turvy . . . I decided to get a grip. Not only had I packed on 15 post-menopausal pounds (too much of it settled around my middle), my energy lagged, and I felt gloomy and glum a lot of the time. Even worse, I started to think that midlife wasn't going to be so great after all. For the first time in my life, I had a bad attitude.
