I never had a flat belly except two times in my life and I was pregnant. I do not gain weight, like a little. I have always tried to eat right and say in shape. Love to exercise from top of my head down. I am 92 at the endof March and people say I am lying when I tell them that. As if I would lie older. I enjoy learning what is best to eat and trying to keep up. Am now getting back into a special top to bottom exercise program and get shapely and firm again. Thanx for your great content.
