First of all, in fact, countless studies show that cigarettes contain a lot of carcinogens, and if they are smoked for a long time, they will really have an impact on the body. And some people smoke every day because they live longer. That's still a genetic problem. For example, a person eats some unhealthy things every day, lives irregularly every day, smokes and drinks every day, and so on. After a long time, his body will have a submissive function, and his body will feel that these are normal, even if it is all kinds of death, his body will not reject it. If we follow the feudal superstition, then this is fate. If we follow the scientific method, this is probably a genetic problem.
Of course, not everyone can have this gene. Don't think this gene is good. First of all, everyone can feel the harm that smoking brings to the body, such as yellow teeth. Dry mouth and bitter tongue, etc., these physiological problems have also greatly reduced their quality of life. And to tell the truth, there are still a few people who smoke for a long time, and we can't use these minorities to endanger our health.
We can look at this problem in proportion. There may not be many people who smoke for a long life, but many people get lung cancer because of smoking. Who will pay attention to those who die young because of smoking? So people who smoke all the year round live longer, but we don't pay attention to people who get sick because of smoking.
In fact, many times, human beings are complex creatures and feel that smoking is neither more than me nor less than me. And I think lung cancer is far away from me, but in fact, if it really happens to you one day, it's too late to regret it, so don't make any bets on your body. The cigarette case has clearly told you that smoking is harmful to health. If you can quit smoking, you should quit smoking early.
