Are you thinking its too late? You figure you have always been big do what is the use. Maybe your parents were big and so I guess you will be, too. Get yourself out of this kind of thinking. Your yesterdays do not have to be your tomorrows. All that needs to happen is you decide to be different than you have been. Take charge of your body and your health. As long as you are alive you can change but once health problems like heart disease creep in its certainly more difficult so don't delay. We are all here for a limited time so don't waste any more of it than you already have. You can do it!
