It is said that smoking is harmful to health, but why do many smokers live into their eighties or nineties?

This problem is mainly due to physical factors. Some people’s constitutions are immune to all poisons, but some people’s constitutions are relatively weak. Even if they don’t smoke or drink, they will still get cancer. Some people’s constitutions are relatively weak. The ability of the lungs to detoxify is several times better than that of ordinary people, so these people will not get sick even if they smoke, and they often live longer.

Everyone knows that smoking is harmful to health, but there are still many smokers who can live to be eighty or ninety years old. For example, my grandma is over ninety years old and smokes more than me. It's amazing, and she doesn't smoke even the good cigarettes bought for her, preferring to smoke some cheap and strong ones. Her health is still good, and she went for a physical checkup some time ago, and the doctor specifically told her not to quit smoking, because her body has become accustomed to smoking every day. It is really possible that you may not get used to it if your intake suddenly stops.

There are actually not a few people with a physique like my grandma’s. Many elderly people are older and have been smoking for many years, but they are still in good health, even if they go The hospital examination showed that there was nothing wrong with the lungs. On the contrary, many people with lung diseases actually do not smoke. However, due to the poor filtering ability of the lungs and daily accumulation, they may develop lung diseases. Moreover, in society nowadays, cancer is more common. They tend to be people who often get angry, so some diseases are not directly related to tobacco and alcohol.

Of course, even if nothing happens to these old people who smoke, it is not an excuse for some people not to quit smoking. After all, such people who are immune to all poisons are still in the minority. Smoking is indeed a big cause of lung disease. The reason is that many people around the world have contracted lung diseases because of smoking, so quitting smoking as soon as possible is the best thing to do.
