Firstly, all the people need to have a healthy lifestyle. People haven´t got it and this is a great problem.
Moreover, I think that you have to do sport every day, don´t eat junk food (especially McDonald´s food) and you hace to drink 2 L of water. If you smoke, or you drink alcohol or take drugs, you need to stop it gradually.
You even need to sleep 7 hours if you are an adult. Whether you don´t rest this time, you are going to feel bad. Personally, when I don´t do it, I´m oblige to think "I´m going to change myself, i´m going to eat well and run every day".
Finally, my advise is that you do all I said before. I hope you will have a healthy lifestyle.
