Write a letter to your friend about telling him how to keep/maintain health

Take my cordial  love. I hope you are keeping well by the grace of almighty Allah. I received your letter yesterday. Then how is your study going on? Are you taking good care of your health? I know you are not so mindful about that. But you must realise that a sound mind remains in a sound body. You must follow the rules of health. You should get up early in the morning and take some physical exercise in the fresh air. You should have a balanced diet. You should also take your meal in proper time and go to bed early. Finally don't forget to keep yourself neat and clean. All of these are necessary for keeping in good health. I hope you will follow these rules of health and enjoy a sound life. Your best friend,
