My mother-in-law who is in her 60's said she never fails to do brisk walking in the morning as a form of her exercise. But she also takes some vitamins or supplements to keep her up. She is in fact taking a diet supplement with acetyl l-carnitine. And I think this will benefit me also because this is not only good for the heart and brain but for other functions of the body as well. It will help me get energized especially that I have many chores to do at home and a baby to take care of. I think it's vital to all of us to give our body utmost importance to stay healthy, alert and physically fit.
