For example many people only drink alcoholics beverages and smoke and take drugs and only do things to tease their body, in this life you must do a lot of sport prepare your body for all the years that await you, you need learn a lot because you´ll need it in your future.

At finally I´m agree with that, if you do in thhis ages all right, it will be better for you. So do a lot of sport, learn all what you can and the most important, life this years.
