I believe it's good because it benifits your body, and it helps the decisions you make. Yoru diet is important because you want to control what you eat. If you eat everything you see that is not going to be good in your adult years. Excersise is good to stay fit, and help work off that extra food you do eat. Overall it's good for your body, mind, and helps reduce the risk of hear disease and cancer. And those do play a big role.
