What do short-lived people have in common? How should we maintain our health after 50? How long will humans live in the future?

Someone asked, what are the common factors that lead to short life after the age of 50?

There is a common saying that goes, "People who live long have their own ways of living long, but people who live short have some common characteristics." This is what I said. So today I will not talk about longevity, but what are the common characteristics of people who live short after the age of 50.

Let’s first talk about the changes in life expectancy throughout history.

From ancient times to the present, the average life expectancy of the Chinese people has been increasing, just like that of all ethnic groups in all regions of the world. According to some statistics, the average life expectancy was under 18 years old during the Xia and Shang dynasties; about 20 years old during the Western Zhou, Qin and Han dynasties; 22 years old during the Eastern Han dynasty; 27 years old during the Tang dynasty; 30 years old during the Song dynasty; 33 years old during the Qing dynasty; and 35 years old during the Republic of China.

Some sources also believe that the average life expectancy in the Qing Dynasty was over 45 years old. There are many reasons why the average life expectancy in ancient times was so short, the most important of which were the high birth and death rate, the large number of casualties in wars, and the weak ability to resist natural disasters and plagues. If the birth rate and other factors are excluded, there were still many people who lived to be over 50 years old at that time. However, there was a saying in ancient times that people over 70 are rare, which means that there were relatively few people over 70 years old.

After the founding of the People's Republic of China, the average life expectancy of the population increased rapidly, reaching 57 years in 1957, 67.7 years in 1981, 68.97 years in 1985, and 72.5 years in 2000. According to statistics released by the World Health Organization, in 2019, Japan ranked first in terms of life expectancy per capita, with an average life expectancy of 83.7 years, including 86.8 years for women and 80.5 years for men; Switzerland and Singapore ranked second and third, with average life expectancy of 83.4 and 83.1 years respectively; my country ranked 57th, with an average life expectancy of 76.1 years, including 77.6 years for women and 74.6 years for men.

Therefore, if a life expectancy of 50 years was considered acceptable for ancient people, a life expectancy of 50 years for modern people is considered short.

What do people with short life spans have in common? I think it is nothing more than these few hard indicators, which are the key factors affecting people's life span.

1. Genetic problems.

Some families have some gene defects, which will be passed on to the next generation or the next generation obviously or implicitly. These gene defects mainly lead to some genetic diseases, such as cancer, hypertension, diabetes, Parkinson's disease, Alzheimer's disease, etc. With these diseases, life expectancy will of course be limited.

Some genes are dominant, and as long as one parent has this defect, it will be easily passed on to the children; some genes are recessive, and if one parent has this defect, it is generally not passed on directly to the next generation, but is inherited from the previous generation; or if one parent has this defect, it will not be inherited, but if both parents have this defect, the next generation will have a greater chance of developing the disease.

This is also the reason why we do not advocate marriage between close relatives. Because of the close blood relationship, the husband and wife are likely to carry the same gene defects, which increases the risk of disease for the next generation. In the animal and plant world, modern breeding uses hybrid advantages, which is essentially a mechanism that promotes each other's strengths and avoids each other's weaknesses, so that the next generation will be healthier, stronger and more productive.

With the continuous deepening of genetic science research and discoveries, human beings have a deeper understanding of genetic inheritance, and the ability to prevent some genetic diseases is also constantly improving. In the foreseeable future, genetic diseases will be curbed and life expectancy will be greatly improved.

2. Life should be regular.

A scientific and regular life is conducive to health and longevity. The scientific and regular life I am talking about here is not the health-preserving sutras that some people talk about, such as working from nine to five, going to bed early and getting up early, eating three meals a day, eating well in the morning, full at noon, and less at night. These seem to be the lives of ancient people. Many people today cannot do these things at all due to their work and life habits. In fact, it is not necessary to do this to ensure good health.

Generally speaking, if you pay attention to the following issues, you will find a pattern:

First, ensure adequate sleep.

Some people like to go to bed early and get up early, while others like to go to bed late and get up late. The work and rest time may be different depending on the job, but as long as you get more than 7 hours of sleep every day, it will be fine. Some so-called "experts" always like to talk about biological clocks. Of course, organisms have their own rhythms of survival and life, but they develop certain habits to live comfortably, and this is everyone's biological clock.

Second, you must have a regular diet, which means eating on time and ensuring nutrition.

The so-called eating on time does not mean that you must eat breakfast at 7 o'clock, lunch at 12 o'clock, and dinner at 6 o'clock. Some people do not have the conditions to eat at these times, what should they do? What should some people do if they work until 3 o'clock in the evening and get up at 10 o'clock in the morning? There is nothing wrong with eating breakfast at 11 o'clock, dinner at 5 or 6 o'clock, and eating some fruit snacks at midnight. If this becomes your routine, you should basically abide by it. In the long run, your body organs will adapt and will not be damaged by fatigue.

No matter what time you eat, you must ensure that you have adequate nutrition every day without overeating. What is nutritious? It means how much protein, vegetables, carbohydrates, vitamins, calcium, etc. should be eaten, and how to supplement them is well. There are many materials that introduce this, so I won't go into details here.

But some bad habits must be controlled. Tobacco and alcohol are both carcinogens, which has been confirmed by the World Health Organization, so if you can quit, try to quit, and if you really can't quit, drink less. For example, some people drink only a small cup a day, and it seems to have little effect, and some even say it will prolong their lives. Although I don't agree with it, it is certain that this way of eating will cause less harm to the body.

Some people are different. They say they won't drink anymore, but once they encounter a fight, they turn around and attack without restraint. Some people are normal only in the morning, but in the afternoon they smell of alcohol and it's impossible to communicate. I have never seen such people without health problems. How can they live long?

Third, health preservation should be scientific.

Some people blindly pursue so-called health preservation. Most of the health preservation promoted now is nonsense without any basis. They regard tree bark, grass root, snake, insect, ant, beast, dog treasure and deer penis as treasures, soak them in wine or stew them in soup, and imagine that they can live a hundred years. Little do they know that the health preservation effect of these items has never had any basis or case proof, but is passed down by word of mouth. The World Health Organization has long announced that Chinese herbal medicine contains toxins, which can lead to kidney failure, liver cirrhosis, cancer and other consequences.

Some people often get themselves covered in bloodstains, and massage and cupping have become commonplace. In fact, many folk massages have no scientific basis at all, and many people have damaged their cervical and lumbar vertebrae, and some have died; cupping is to burn the oxygen in the cup with fire, and through vacuum negative pressure suction, the subcutaneous capillaries are broken, and bruises are caused by subcutaneous bleeding.

There has never been any statistical data on how many diseases these methods of health preservation have cured, or how many people have lived longer. You can just look around at your relatives, friends, or people you know or don't know. How many of those who advocate these bad habits have a smooth life? How many have achieved health and longevity?

Some people always like to take some traditional "tonics", but in fact no one knows what they really provide.

Let’s talk specifically about bird’s nest here.

Bird's nest, to put it bluntly, is a nest made of swallow's snot and saliva mixed with some bird feathers. However, this kind of swallow is not common in my country. It mainly lives in coastal islands in Southeast Asia. Modern analysis shows that it is mainly protein, with a little calcium and amino acids. In fact, human saliva and snot are also these things. A search on Baidu will show that human saliva mainly contains mucin, mucopolysaccharide, amylase, lysozyme, immunoglobulin, amino acids, etc.

If a little protein is considered high-level nutrition, then dog shit is also nutritious. In addition to shed cells and bacteria, feces are mostly protein, organic matter, fat, undigested fiber, etc., and also contain many vitamins. No wonder some ancient books also use feces and urine as medicine, but whoever wants to eat it can eat it, anyway, I stay away from it.

In fact, the rock sugar bird's nests sold in the market for hundreds of yuan a box or several bottles, the contents of which are not even equal to two eggs or a box of milk. Some people insist on spending a lot of money to buy such things. I can't say they are stupid, I can only laugh. What are the benefits of eating these? I have never seen any. If there are really benefits, why didn't the kings and ministers in ancient times eat them? Didn't Qin Shihuang eat them? He still had to seek immortals and refine immortals to prolong his life? He could only live to 51 years old.

Lin Daiyu was sick and ate a bowl of bird's nest porridge and ginseng every day, but she didn't live past 17. The book says that she had been taking these "medicines" every day since she was a child. It is very likely that she ate too much of these toxins, such as grass roots, tree barks, bird's nests, ginseng, etc., which damaged her liver and kidneys and eventually died of exhaustion. Some people say it was tuberculosis, which can be cured with antibiotics now, but the "miracle doctors" and "miracle medicines" of that era were useless. The problem is that some people now squat in the golden nest of modern science, but they still insist on going back to the past and pursuing these garbage, which is ridiculous and pathetic.

Therefore, a modern and regular scientific life means learning more modern scientific common sense and not foolishly pursuing garbage.

In terms of diet, chicken, duck, fish, meat and eggs are the main sources of protein, vegetables and fruits are the main sources of vitamins, and meat and milk are the main sources of calcium. A balanced diet and a good control of the amount of food intake, not too much or too little, is scientific health care.

If you have any health problems, you must go to the doctor. After the age of 50, you should have a physical examination at least once a year. Early detection and early treatment of diseases can nip serious diseases in the bud. I must say it three times. You must go to a regular hospital for medical treatment. You must go to a regular hospital. You must go to a regular hospital. Never believe in quack doctors, itinerant doctors, folk masters, etc. who boast about their health. Few people who believe in such people will have good results.

Proper exercise is also an important part of staying healthy. The so-called moderation does not mean that you should walk a lot or run a lot, or do some kind of boxing or exercise, or develop a mermaid-like waistline. Especially after the age of 50, it is enough to exercise for half an hour or an hour every day. Don't fall asleep or sit still all the time. It's enough to sweat a little or feel comfortable when exercising.

3. Follow the rules when doing things.

The rules here are the bottom line, not the big words such as morality and dedication that some people often talk about. There is no standard for such big words. Whoever has the right to speak has the final say. The rules I am talking about are social conventions and some laws and regulations.

For example, don't drink and drive, and don't drive after drinking; for example, walk on the sidewalk when crossing the road, go on green lights and stop on red lights, etc. In social life, in the interaction with relatives and friends, we must abide by social order and emphasize fairness and credibility. For example, if you borrow money from others, you must pay it back on time. If you really have difficulties, explain it clearly to the other party and apologize, don't hide from them; for example, when friends get together for dinner, even if you can't take the initiative to treat others, you must return the gift if you accept someone's invitation. You can't always eat other people's food and never return the gift.

Also, people should be trustworthy. What they say should be put back on the table. Don't brag and forget about your promises, pretend to forget, or avoid the matter. These are the basic requirements and bottom line of following the rules.

If you don't have this bottom line, for example, you always drink and drive, thinking that as long as you are not caught by the traffic police, it's fine; you always cross the road instead of walking on the sidewalk, and always run red lights. This kind of non-compliance with the rules may not always lead to accidents, but the probability of accidents is hundreds or thousands of times greater than that of people who abide by the rules, and the probability of longevity is hundreds or thousands of times smaller than that of people who abide by the rules; and those who do not abide by the conventions in social interactions will make you live a wretched life, be disliked by others, and finally be deserted by friends and relatives, and your mood will not be good, and you will not have the chance to live a long life.

Of course, there are many more rules to talk about in life, and it is impossible to list them all. They can only be understood but not expressed in words. Just experience it yourself.

In short, the above three points are the key to whether people will live long after they are over 50. If you follow them well, you may live long, otherwise you will shorten your life. Although genetic problems cannot be completely solved by yourself, some studies believe that the influencing factors of most genetic defects are less than 50%, and the other 50% are affected by acquired environmental factors. Therefore, as long as we work hard on the latter two aspects, no matter whether the genes are good or not, longevity is expected.

How much do you know about longevity in the future?

The average life expectancy of Chinese people is now approaching 80. I hope that friends who read this article will be able to exceed this average life expectancy in the future. However, this is not the end.

Not long ago, the world legend, SpaceX boss Musk made another astonishing statement, saying that humans can achieve immortality in the near future. He believes that there are two ways to achieve immortality: physical immortality, which is to repair the human body through genetic technology and nano-robot technology, greatly extending the life span of people; and non-physical spiritual immortality, which is to discard the physical body through uploading and transferring human consciousness.

Musk believes that physical immortality will take up a lot of resources, and that population explosion will eventually lead to human extinction. He is working on the development of immortality through mind uploading, and has threatened to surpass the physical immortality technology being developed by the Google team in time to save humanity from extinction. I am not sure whether these statements are wild or true. But at least it can be expected that in the near future, human life expectancy will be greatly improved.

Therefore, as long as people over 50 start living according to scientific methods from now on and live healthily for 20 years, new technologies will be available to help you live longer. I look forward to a better tomorrow for mankind with everyone.

That’s it, welcome to discuss, thanks for reading.
