If people only drink beer, some people will sick because beer is unhealthy drinks. Milk is a good drinks, but don't drink a lot because if you drink a lot of milk, your body will has too much protein that can't used to help you grow, it will makes you more fat. I think if beer instead of milk, there won't have anybody want to tame cow, because we don't needs to tame cow. There won't have cheeses. I likes to eat cheeses. If someone drank, he will use gun to shoot at someone. Children can't drink beer, they need milk to help them to grow better.
