If you don't smoke or drink all your life, will you live longer? A study gives the answer.

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'm sure you've heard many such sayings 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 confused. Why can some old people live for a long time after smoking and drinking?

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

1, genetic talent

The tobacco and alcohol personnel of the University of California once conducted a survey on this issue, comparing more than 100 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 period of experiments, researchers found that smokers who live longer have shorter telomeres and stronger repair ability, and can offset the harm caused by tobacco and alcohol with their own talents.

In other words, these people who smoke and live longer have genetic advantages, but it doesn't mean that smoking and drinking won't do 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's better not to smoke or drink.

There is no single reason for longevity.

In fact, smoking does not completely determine the length of life. People's life 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 died of related diseases, and the average life expectancy of smokers was shortened by ten years compared with that of non-smokers. The harm of alcohol to human body is not bad. The more you drink, the more harm you do to your health.

To sum up, it is very unscientific to say that smoking and drinking will make people live longer. In fact, the really long-lived old people 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 rejection of meat will easily lead to protein deficiency, anemia, myasthenia and other symptoms, and 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 one.
