How tall we should grow？
Nature's most remarkable and miraculous creation is none other than human beings, who are called the spirits of all living things.We may be too small compared to a long whale or elephant, but we are as tall as an insect or vole. We are taller than insects and mice. We exist in the right size for nature's purposes.
From one and a half to two meters, that is the height range of billions of men and women on the planet, and the proliferation of Giants and midgets often set new records for human height and shortness. The two-point-seven-two-meter-tall U.S. man Robert and the zero-point-two-meter-tall U.S. man on the Guinness Book of World Robert, a 2.72 meter tall American man, and Pauline, a 0.48 meter tall Dutch woman, can be considered the upper and lower limits of human height in the world. The upper and lower limits of the world's human height.
Even if we open the old books, it is not difficult to find such things as great, sturdy, seven-foot man, Angzang Husband, tiger body brawny body, gold steel pagoda and other words of praise of tall people. It can be seen that people despise short and pursue tall The mentality of pursuing tallness has not started since today. It is a deep-rooted belief that tall means healthy, strong, powerful and handsome.
As for some contemporary girls, when seeking a spouse, they declare men under 1 meter 70 as second-class invalids. It can be said that the style of greed for height and length has been carried to the extreme.
The research results in response to this mentality are coming out all the time. The methods of teaching people how to grow taller were also varied and There are many different ways to teach people how to grow taller. However, have we ever seriously considered how tall humans should be?
Let's start with something unrelated that might help open our minds. Here is an ordinary piece of tofu, which is well It keeps its shape very well. But what would happen if we made it bigger, and bigger still? Voila! The bean curd collapses! The implications of this test are clearly not good for the big guy. So, is the tofu too weak to What is the problem?
Let's just take a hard rock as an example. Even if a mountain made of granite, can it increase in height indefinitely? Calculations Calculations show that on Earth, the critical height of a mountain is eleven kilometers, and if it exceeds this limit, it is difficult to be "stable as a mountain".
The enormous shear stress would break through the strength limit of the rock, causing the mountain to sink and collapse. In fact, the world's first Everest reaches only nine kilometers high.
Simple mathematics tells us that as the linearity of an object increases, the surface area increases by the number of squares, and the volume increases by the number of cubes. (a) If a flea is enlarged ten times as it is, the result will never be that it can jump up a large tree. If a swallow is enlarged ten times, it will no longer be able to dance freely; if a mouse is enlarged ten times, it will no longer be able to fall from a high building unharmed. If there are really giants in fairy tales who are several feet tall and powerful, let's just count them as ten times taller than ordinary people, their weight will reach eighty tons, that is, a thousand times the normal human, while the cross-sectional area of the bones but only a hundred times. So these clever giants will be pressed by their own weight to struggle, and even broken tendons
Bone fracture, where can we talk about to pull up mountains and lift a tripod, force sweep a thousand troops?
Look at the real-life giants that hobble, slow action, it will be understood that the tall body is enough to make the human flexibility and agility is greatly reduced. And the skin area can not grow in the same proportion as the weight, naturally brings This is the reason why people with large bodies are especially afraid of heat.
The problem goes far beyond this. We know that giraffes need to use 260 cm high mercury column of blood pressure in order to put blood to the head, and taller people undoubtedly need higher blood pressure and tougher blood vessels to avoid a lack of blood supply to the brain. Insufficient blood supply to the brain. Longer limbs can lead to poor venous return and poor peripheral circulation, not to mention that a large body requires The large body requires more blood supply. In this way, people who have acquired the reputation of being big and tall have to increase the burden on the cardiovascular system as a substitute. The price of this is the increased burden on the cardiovascular system. In fact, the simultaneous increase in burden also includes the digestive, respiratory, urinary and all other systems. Take the nervous system, for example, consider that the dinosaur's tiny head managed a body weighing tens of tons, making it
a classic management failure in the history of biology. If our heads are burdened with a body that is too large in proportion, it will undoubtedly will also lead to an overall decrease in our own management level.
The list of physiological difficulties caused by a large body could go on and on. Detailed statistics point out that human life expectancy and height have a definite functional relationship. The elderly do not prefer tall people, but often favor The elderly do not prefer tall people, but often prefer people of short stature. A survey of 88 centenarians in Hubei province showed that their average height was 143 cm and their weight 38 kg. The survey report listed "thin body" as the first factor for longevity, a conclusion that coincides with the findings of scholars around the world. This conclusion coincides with the research findings of scholars around the world.
If you look around at your relatives and friends, it is easy to see that the human figure is tending to increase. The trend is to increase the size of human beings. Some people assert that the ancient people were taller than the present people based on ancient books such as "a seven-foot body". This is actually a misunderstanding caused by the fact that the ancient scale was smaller than today's and the exaggerated depiction in literature. The skeletons excavated in ancient tombs and the clothes left behind by ancient people clothes left behind confirm at a glance that the height of historical figures was significantly smaller than that of modern people. And in the last hundred years, accurate accurate statistics have made it even clearer that the average height of humans worldwide is increasing at a rate of one centimeter per year. The average height of human beings around the world is increasing at a rate of one centimeter per year. Among them, we Chinese are late to the party, but we are coming hard. This phenomenon of
This phenomenon of generational height is attracting widespread attention from governments and scholars.
Many scientists have attempted to provide answers to this phenomenon: adequate nutrition, improved medical conditions, rising carbon dioxide levels on the earth, and electromagnetic radiation. The increase in carbon dioxide levels on the earth, the increase in electromagnetic radiation doses, the increasing frequency of human migration and mobility, and especially the The real reason for the continuous growth of human height remains to be further explored and confirmed. ...... The real reason for the continuous growth of human height remains to be further explored and confirmed.
The rise and fall of other species in the history of life on earth cannot help but cause humans to think seriously about their own fate. Paleontologists tell us that the ancestors of dinosaurs were originally small, and after hundreds of millions of years of continuous growth, they finally After hundreds of millions of years of growing fat, they finally became the most massive animals in the history of life and went on the road to poverty. The elephants, giraffes and pandas in the world today They all had flexible and small bodies at the beginning, but as generations expanded themselves, they were gradually reduced to rare and protected animals. As they have expanded over the generations, they have been reduced to rare and protected animals. This shows that the increase in body size is not conducive to the survival and reproduction of species. The rate of carapace enlargement proposed by French paleontologists De Paré and Mouret reveals this. This law of life is revealed by the rate of animal carcass enlargement proposed by French paleontologists Depare and Mouret. Shouldn't mankind learn from the historical lessons of the decline and extinction of many species? Shouldn't mankind be highly alert and reflective from the historical lessons of the decline and extinction of many species?
Let us now turn our attention away from scientific theories and look at the social reality to see how human height The growth of human height will bring a series of problems. First of all, food is the key to people's lives. According to calculations, the average increase in human height of 30 cm, it will consume 50% more food. And the consumption of clothing and fabrics will also increase alarmingly. If If a person's feet are one-third larger, just one United States each year to make shoes will use up an additional 10,000 square kilometers of leather. At the other end of the consumption spectrum, there will be a proportional increase in waste and pollution. The economy of human society will be unaccountably The economy of human society will unknowingly be subjected to this unexpected pressure.
When we made family planning a national policy, we probably seldom thought that if the height of each Chinese person increased by one percent, the weight would increase by one percent. If each Chinese person were to increase in height by one percent, the corresponding increase in weight would be three percent, and the result would be the equivalent of feeding 30 million more people. How much of the family planning The results of family planning have been invisibly eliminated.
A more profound consequence is that people are the measure of everything, and when the measure changes, everything changes. The increasingly taller Humans will no longer feel comfortable with the living environment created by their predecessors. Houses are lower, furniture is shorter, the passenger compartments of cars and boats are narrower, and the tools of production do not fit. The cabin of a car or boat is cramped, and the tools of production do not fit in the hand. Recently, the seats of many old theaters in the United States can no longer accommodate the taller Many old theaters in the United States have recently been forced to redecorate their seats because they can no longer accommodate the taller, younger generation. The French airline Condor has reduced the number of seats on its planes due to the increased weight of its passengers, resulting in a loss of $2 million in annual profits. The French airline Condor is losing $2 million a year in profits due to the reduction of seats on its planes as passengers gain weight. Doctors are considering the need to increase the dosage of pills so that the generally taller patients don't take them at a lower strength. The pills are not strong enough for the larger patients. It's hard to envision a day when humans will replace the countless achievements of our existing civilization, just as they have replaced their smaller clothes.
the countless achievements of our existing civilization.
In 1956, when Mr. Yinchu Ma proposed the theory of population control, society, due to ignorance and prejudice, failed to give it the attention and recognition it deserved. society, due to ignorance and prejudice, failed to give due attention and recognition to this theory. Today, when the educated people of the nation, with a sense of responsibility to strengthen the country and the race, advocate for a red light to be put on the rapid growth of height red light on the rapid growth of height, can we just dismiss it as alarmist nonsense and self-concerning worry? The human race is capable of moving from freedom to freedom.
Human beings are the only species that can move from freedom to self-reliance. It is time to change our blindness to the natural and even artificial acceleration of height growth. It is time to change our blind attitude and dangerous approach to the natural and even artificially accelerated process of height growth. Visionary scientists, philosophers, politicians, economists and futurists should work together to find the solution to the optimal human body size from a higher order equation with numerous constraints. The solution to the problem of optimal human fitness from a higher order equation with innumerable constraints.
The distinguished economist Schumacher said, "Man is small, and small is beautiful; to seek to be large is to commit suicide. "At least for the time being, we need to start reversing the misguided concept of human eugenics and revise our aesthetics regarding health and marriage. and marriage, and to rethink solemnly what we should become in the future on earth. We need to begin, at least for the time being, to revise our aesthetic code of health and marriage and to rethink seriously what kind of people and human beings we should be in the future.
