For most of my life, I have not had to care much about what I eat. My metabolism was pretty fast, and so I did not gain any weight. Moreover, my life was active, and so I tended by burn calories. I know that when some people watched me eat, they resented that I could eat so much and gain so little. All of that changed when I turned 50. Suddenly I had to pay attention to my diet. My metabolism slowed and my gut grew. It was a moment when I had to make a decision.
