I TURN 50-YEARS OLD IN SEPTEMBER and next to the anxiety of spending that day alone, I’ve always been anxious about not staying in shape. So I work out like crazy, and its not braggadocio: I am in the best shape of my life and for the last year I have not had a single bad workout. Kicked off last year by the demise of a long relationship, the ensuing depression killed my appetite for several weeks, which jump-started my metabolism, and the anger and sadness over getting destroyed fueled my motivation in the gym. Couple that with having more spare time, realizing then that working out is the only guaranteed thing that will change my mood, every time – endorphin and serotonin are very powerful – and I really do enjoy it, I’ve never felt better. Plus, I’ve changed my diet, cut out really cut down my sugar intake (sugar is EVERYWHERE!) and the sum total is I dropped over 20 lbs., have kept it off, look better, and feel great.
