Telomere slogan

Alcohol and tobacco are harmful to health, which is a well-known slogan. However, there are still many people who smoke and drink unscrupulously. Moreover, people often cite some examples of people who smoke and drink but live longer to refute this statement. They think that alcohol and tobacco will shorten life expectancy.

I believe you have heard a lot about this statement in your life. Although all kinds of authoritative organizations and countries are promoting the harm of alcohol and tobacco, there will always be old people who are covered in alcohol and tobacco but live long. If they don't drink, will their life expectancy really be shorter?

Do people who don't touch alcohol and tobacco live longer or those who touch alcohol and tobacco live longer?

In fact, in order to solve this problem, China also conducted a four-year survey. In this study, the researchers conducted a follow-up survey of more than 300 centenarians in various regions of the country and wrote a research report. According to the report, most centenarians have very healthy living habits, and the proportion of non-smoking and non-drinking is as high as 75%.

It can be seen that there is an obvious correlation between not smoking and not drinking and longevity. Not smoking and not drinking will really make your body healthier, thus prolonging your life.

At this time, some people may be very puzzled. Why do some old people live a long life after smoking and drinking?

Why do some old people live longer after smoking and drinking?

1, genetic talent

Tobacco and alcohol researchers at the University of California once conducted a survey on this issue, comparing more than 65,438+000 long-lived elderly people who smoked for a long time but were over 80 years old with more than 700 long-term smokers who lived less than 70 years old.

After a long experiment, the researchers found that long-lived smokers have shorter telomeres and stronger repair ability, and they can use their talents to offset the harm caused by tobacco and alcohol.

In other words, these people who smoke for a long life have genetic advantages, which does not mean that smoking and drinking will not cause harm to the body, and we have no way to judge which state our genes belong to, so for the sake of good health, it is best not to smoke and drink.

There is no single reason for longevity.

In fact, smoking does not completely determine the length of life. People's life span will also be affected by other factors, including climate, environment, diet and other conditions. Under the comprehensive effect of these factors, people's final life can be determined. Therefore, it is very one-sided to just watch them smoke and drink, and it is even more undesirable to be partial.

3. Survivor bias

According to WHO statistics, about one-third of smokers die of related diseases, and the average life expectancy of smokers is ten years shorter than that of non-smokers. Alcohol does great harm to human body. The more you drink, the more harmful it is to your health.

In a word, it is very unscientific to say that smoking and drinking will make people live longer. In fact, old people who really live long often have these characteristics.

The * * * characteristics of the long-lived elderly may be worth learning.

1, good eating habits

In fact, the influence of diet on life expectancy is beyond people's imagination. The survey mentioned in the last article found that the diet of most centenarians is very healthy and the collocation of meat and vegetables is very reasonable.

Many elderly people prefer vegetarianism and think that eating more vegetables will make them healthier. Long-term refusal to eat meat can easily lead to the lack of protein, resulting in anemia, myasthenia and other symptoms, which will also bring many diseases to the body and threaten health.

2. Proper exercise

Many centenarians have the habit of walking. Indeed, life lies in exercise. Regular exercise can not only accelerate the excretion of toxins in the body, but also keep metabolism and blood circulation in a relatively healthy range, making the body healthier.

However, with the growth of age, the physical function of the elderly is declining, so it is best to choose the exercise that suits you. Walking is a very good exercise.
