Tobacco and alcohol are harmful to health is a propaganda slogan that everyone can hear, but there are still many people who smoke and drink unscrupulously, not only that, but also often cite some examples of people who smoke and drink but live a long life to refute this sentence, thinking that tobacco and alcohol do not stick to but have a shorter lifespan.
I believe that you have heard a lot about this statement in your life, although various authoritative institutions and countries are publicizing the harm of tobacco and alcohol, but there will always be old people who are very long-lived when tobacco and alcohol are all stained, is it true that the life expectancy of dripping alcohol is shorter?
Do people who don't touch alcohol and tobacco live longer or do people who touch alcohol and tobacco live longer?
In fact, in response to this problem, China also conducted a four-year-long investigation and research, in this study, researchers in various regions of the country to track more than 300 centenarians, and wrote a research report, the report pointed out that most of the centenarian living habits are very healthy, of which do not smoke and do not drink the proportion of people up to about 75%.
It can be seen that there is indeed a clear correlation between not smoking and not drinking alcohol and longevity, and not sticking to tobacco and alcohol will indeed make the body healthier, thereby prolonging life.
At this time, some people may be very confused, why do some elderly people smoke and drink, and still live for a long time?
Why do some old people still live a long life with tobacco and alcohol?
1. Genetic talent
Tobacco and alcohol personnel at the University of California once conducted a survey on this issue, comparing more than 100 long-term smokers but over the age of 80 and more than 700 elderly people who also smoke for a long time but live less than 70 years.
After a long experimental process, the researchers found that long-lived smokers have shorter cellular telomeres in their bodies, have stronger repair ability, and can use their talent to offset the damage caused by tobacco and alcohol.
That is to say, these smokers and longevity people have a genetic advantage, not that smoking and drinking will not cause damage 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 better not to smoke and drink.
2, longevity reasons are not single
In fact, smoking can not completely determine the length of life, human life will also be affected by other factors, including climate, environment, diet and other conditions, under the comprehensive action of these factors, can determine the final life of people, so just look at whether to smoke and drink This condition is very one-sided, and it is not advisable to generalize.
3. Survivor bias
According to WHO statistics, about one-third of smokers die from related diseases, the average life expectancy of smokers is also ten years shorter than the average lifespan of non-smokers, and the harm of alcohol to the human body is also very similar, the more alcohol is drunk, the greater the damage to the body.
And people see the elderly who smoke and drink but live very long, more of a kind of survivors, for those who die because of this, few people will really pay attention, so they have become the invisible majority, and those who live long are more of a survivor bias, can not be included as effective data in the scope of statistics.
In summary, smoking and drinking alcohol will make people live longer is a very unscientific statement, in fact, the real longevity of the elderly, often have these common characteristics.
The common characteristics of long-lived elderly people may be worth learning
1. Good eating habits
In fact, the impact of diet on life expectancy is beyond people's imagination, and the survey studies mentioned above have found that most centenarians have a very healthy diet and a very reasonable combination of meat and vegetables.
Many elderly people prefer vegetarian food, feel that eating more vegetables will make the body healthier, long-term rejection of meat can easily lead to a lack of protein in the body, resulting in anemia, muscle weakness and other symptoms, but also to the body to bring a variety of diseases, threatening physical health.
2. Proper exercise
Many centenarians have the habit of walking, indeed, life lies in exercise, regular exercise can not only accelerate the discharge of toxins in the body, but also keep metabolism and blood circulation in a relatively healthy range, so that the body is healthier.
But with the increase of age, the elderly's physical functions are declining, it is best to choose the right exercise for themselves, of which walking is a very good.
