If you see your friend eating junk food, what will you say to him and what advice will you give him-no less than six sentences.

First, you show him the video; Second, you collect junk food instructions; Third, you know a little chemistry and write down the open chemical molecular formula of food additives; Fourth, you tell him what nutrition your body needs. On the basis of such facts, you can have a good talk about this problem. Men won't listen to other people's advice and won't stop until they wake up. That's what I do.
