The Secret of Long Life for Old Smokers Foreign media said that a study on smokers over 80 years old showed that some special properties in their genes made them respond to the health hazards of tobacco in a different way from others, thus helping them live longer.
According to the report of Latin America News Agency on September 12, French Jeanne Karman is considered one of the oldest people in the world. She died at the age of 122. Although the woman continued to exercise until she was 100 years old, her body was not very healthy, because she had smoked two cigarettes every day since she was 21 years old, and this habit remained until she was 120 years old.
Morgan Levin, a human gene expert at the University of California, Los Angeles, who is in charge of the study, said that from a biological point of view, the genetic genes of those who have similar habits with Calman are special.
Levin pointed out that researchers have found a set of genetic markers that can promote longevity. He believes that there is evidence that this group of genes can improve human life expectancy by increasing cell maintenance and repair.
Therefore, although some people are under various biological pressures for a long time, such as tobacco, their bodies seem to have the ability to better cope with the damage caused by these risk factors and repair them.
Levin pointed out that finding the gene code that promotes longevity in the genome of elderly smokers will help human beings extend their life span and avoid various diseases and physiological defects.
Smoking is lung cancer Important inducement of
Smoking is lung cancer The risk of lung cancer is higher for long-term heavy smokers than for ordinary people. Even so, some people continue to "swallow clouds and puff fog" with fluke mentality.
Family history of lung cancer, long-term smoking, long-term exposure to second-hand smoke, and long-term exposure to smoke and dust during work are high-risk groups for lung cancer. Of course, clinically, people who have healthy lifestyles and no family history have suffered from lung cancer. In fact, everyone carries cancer Gene, whether the disease is caused or not is related to autoimmune function, air pollution, etc. However, in general, high-risk groups are more likely to suffer from lung cancer. Therefore, we suggest that everyone should develop a healthy lifestyle, try to stay away from alcohol and tobacco, ensure sleep, and do more exercise to reduce the risk of lung cancer.
In medicine, smoking index is used to express the relationship between cumulative smoking and lung cancer. Smoking index=number of cigarettes per day × number of years of smoking. If a smoker smokes 20 cigarettes a day for 20 years, his smoking index is 20 × 20=400. If the smoking index is>400, he should be included in the risk group. If a year is calculated as 365 days, it means that after 7300 packs of cigarettes, the risk of lung cancer will be greatly increased.
Because the lung tissue has no pain sense nerve, lung cancer patients usually do not feel obvious symptoms in the early stage, and metastasis has occurred when the body has cough, low heat, blood in sputum, chest pain and other symptoms. It is suggested that everyone, especially the high-risk group, should conduct a low-dose CT screening for lung cancer once a year. If CT finds shadows or nodules in the lungs, it is better to go to a regular large hospital to find an experienced respiratory doctor for careful examination.
