Why does my father like smoking so much?

Smoking is a bad habit, but now many people smoke, although the harm is not great, but smoking too much will lead to a high incidence of lung cancer.

You can tell your father that a scientist made an online survey-the incidence of lung cancer is 70% for people who smoke two packs of cigarettes a day-that is, 7 out of 10 people will get lung cancer, and it is incurable-and your father will pay attention to smoking less.
