“Physical Fitness is not only one of the most important keys to a healthy body, it is the basis of dynamic and creative intellectual activity. The relationship between the soundness of the body and the activities of the mind is subtle and complex. Much is not yet understood. But we do know what the Geeks knew: That intelligence and skill can only function at the peak of their capacity when the body is healthy and strong.”-President John F. Kennedy  

It is important to take care of yourself. You'll feel better if you do. When you're sick or when you have a headache, you can't concentrate. You don't feel like doing anything. Now imagine feeling that for a real long time just because you didn't take care of yourself. It would be terrible wouldn't it? That's why you have to take precautions and take care of yourself. If you don't im sure many thing will change. You grade will go done, you'll be frustrated, you'll feel pressured and many more things that aren't good. You can start making a change to your life if you don't want this. Eat healthy; vegetables,fruit, grain and etc. Stop eating so much fast food or junk food, it can make you sick. Junk food and/or fast food can make you gain weight, that's not good. So if you do feel like you are overweight you should exercise. Even if you're not overweight you should still exercise, its good for you. Start making changes to your lifestyle, changes that will benefit you.
