My boy looks like my father, but my classmates say that my son is as short-lived as his father, but he can't live 18, but I'm still alive 19. Why?

You are a boy. Looks a lot like your father. But your classmate said that his son is as short-lived as his father and will not live to 18. Now you 19 years old. What do you think they will say? Is it a little superstitious? Are children as short-lived as their fathers? This is a bit unrealistic. There are many people and boys like their fathers. They are all alive and healthy, and their lives are short and long. They don't rely on looks to be alert, but need your healthy body. And your unhappy attitude. It doesn't matter who you look like. What matters is whether you are healthy or not. Are you sick? Like some people who have cancer, they are still alive and well, because they have a good attitude, adjusted their attitude very well and put everything down. Adjust your mood and live happily every day. This is what we should do. We should grow up happily. If someone is ill, he should go to the hospital early. Don't deal with a minor illness before it becomes a serious one. You are now in the sun, and children aged 19 are the happiest. Study hard and don't think about anything else. Those words are superstitious and have no scientific reason. So, don't take these things to heart, study hard, have your own career in the future, do your own career well and be a happy and kind person.
