The Amazing Mystery of Old Smokers: Smoking, Not Suffering from Lung Cancer, Still Living Long? American research reveals the truth!

Everyone knows the dangers of smoking to their health, but we often hear stories like this: an old smoker who smokes all his life but lives a long and healthy life without any signs of lung cancer.

Why on earth is this? Recently, a study in the United States provided the answer.

We must first understand that smoking is the main risk factor for lung cancer, but not all smokers will develop lung cancer.

The relationship between smoking and lung cancer is like tossing a coin, and the results may be positive or negative. Smoking does indeed increase the risk of developing lung cancer, but not all smokers will "throw" the result of developing lung cancer.

This involves our genetic and environmental factors.

In this study, scientists found that some elderly smokers may have escaped the threat of lung cancer due to their genetic makeup.

These people have specific mutations in their genes that can protect them from harmful substances produced by smoking. That is to say, these people's bodies have a self-protection mechanism against harmful substances in tobacco.

There are over 200 single nucleotide polymorphisms in the genome of the "smoking and longevity population", which is more than three times higher than the probability of a hundred year old longevity of ordinary non-smokers. The reason is that this gene has a stronger ability to repair damaged cells and can repair the cellular damage caused by smoking.

In addition, research has found that these old smokers often have a healthier lifestyle. They may pay more attention to diet and exercise, which can to some extent offset the harm of smoking.

In other words, they may receive a "protective umbrella" due to other healthy lifestyles, such as eating reasonably and exercising regularly.

This is not to say that smoking is harmless, or to encourage people to smoke. Researchers have clearly pointed out that although some people can escape the threat of lung cancer due to genetic or lifestyle reasons, this does not mean that smoking is safe.

On the contrary, smoking remains the main risk factor for lung cancer and many other diseases.

In fact, the main purpose of this study is to identify new ways to prevent lung cancer by studying people who smoke but do not have lung cancer.

If we can identify the genetic variations of these people or the secrets of their lifestyles, perhaps we can find new strategies for preventing and treating lung cancer.

However, this does not mean that we can let ourselves go and continue smoking.

Although some people may have escaped the threat of lung cancer due to genetic or lifestyle reasons, this does not change the general health hazards of smoking.

In fact, smoking not only increases the risk of lung cancer, but also increases the risk of heart disease, stroke, and many other diseases.

Therefore, regardless of our genes, maintaining a healthy lifestyle, such as quitting smoking, eating a reasonable diet, and exercising in moderation, remains the best choice for us to maintain health.

Finally, this study reminds us that everyone's body is unique and our resistance to diseases varies.

Some people may be able to escape the threat of certain diseases due to genetic or lifestyle reasons, but this does not mean they can ignore health risks and lead unhealthy lives.

On the contrary, we should strive to maintain a healthy lifestyle as much as possible, which is the best weapon for us to fight against diseases and maintain health.

In summary, smoking is the main risk factor for lung cancer, but not all smokers will develop lung cancer. This may be related to their genes and lifestyle.

However, this does not mean that smoking is safe, or that we can ignore the dangers of smoking. We should strive to maintain a healthy lifestyle as much as possible, which is the best choice for us to fight against diseases and maintain health.
