Therefore, people eat to fill their stomachs, which is only a superficial phenomenon. Eating is actually to maintain the normal activities of the human body and maintain people's life and health.
There is an old saying that "food is also sexual". This sentence is actually equivalent to saying nothing, because you can also ask, why is there such "sex"?
When I was a child, I heard a story. A sour scholar saw snow falling outside the study and improvised a poem: "When it snows and it doesn't rain, it turns into rain when it snows on the ground. It is more troublesome to turn into rain. It is better to rain at the beginning. " The scholar is proud, and he doesn't want a naughty pupil to answer the teacher's song: "Teacher Wang doesn't eat shit when he eats, but when he eats, he becomes shit." Becoming a cockroach is more troublesome. It is better to eat cockroaches at first. "
After listening to the story, I didn't laugh, but I have been thinking seriously. Why do people eat? I don't know if it was to solve this problem, but later I became a doctor. But medical textbooks all say that people need energy and eat to supplement energy. Obviously, this answer still doesn't satisfy me, because middle school physics has said that energy is conserved, energy will not disappear, it will not be produced out of thin air, and how much energy people absorb will be released. Directly connecting with the concept of "entropy" can be regarded as an exact answer to this question: eating absorbs low-entropy substances, defecating expels high-entropy substances, thus maintaining the integrity of human tissue structure.
The introduction of the concept of "entropy" makes many problems in daily life have a brand-new understanding and explanation.
Why do people sleep? This is because the process of absorbing low-entropy substances and expelling high-entropy substances is related to the incomplete balance of people's daily activities, and people must leave a long time for the human body to complete this process. During the day, human activities output a large number of low-entropy flows, including labor and thinking, and the human body produces a large number of high-entropy substances to accumulate in the body. At night, on the one hand, people need to solve a large number of disordered signals absorbed by the brain through sleep and store them in the form of codes. On the other hand, they also need to excrete a large number of metabolites (high entropy substances) in muscle and blood. Obviously, sleep has become a necessary process to maintain the integrity and health of the body structure. Some animals don't seem to need sleep, such as whales, but the whale's brain actually takes turns to sleep, that is, the left and right hemispheres take turns to sleep. It seems that people don't rest, but in fact, people rest while working.
Why do people have sex? This question is tantamount to asking why people are bisexual and why people die.
So why do people choose bisexual reproduction instead of trisexuality or monogamy? This is because three-sex reproduction is too easy to fail and is not a good survival strategy. Parthenogenesis is not as good as bisexual reproduction, which can create rich diversity and produce species diversity to adapt to the changes of living environment and improve the ability of the whole species to cope with disasters and survive. From the point of view of entropy, the genetic material (information, which belongs to "negative entropy") provided by both sexes is twice that provided by monogamy. Obviously, for the whole human being, the amount of structural information increases geometrically, which is undoubtedly beneficial to the continuation and survival of the whole race.
Why do people die? Modern science has proved that human DNA replication (the molecular biological basis of human cell structure metabolism) is limited. Every time a cell replicates, the telomere of a chromosome will be shortened by a section, just like there is a counter on a DNA molecule, and the number of times it can be replicated in a lifetime is limited. When a person is aging, the number of cells in the body can't keep up with the number of deaths, and the tissues gradually lose their vitality. The "entropy" in the human body began to accumulate gradually. At this time, it is more and more difficult to ask him to output more low entropy streams. On the contrary, the elderly are increasingly exporting entropy streams. Specifically, the elderly often do something for the sake of doing it, but the result is counterproductive, making the environment worse. When the entropy in the human body accumulates to a certain extent, but there is not enough ability to absorb more low-entropy flows, the body will gradually collapse and people will die.
It is a fact that the entropy increase in the field of human psychology is synchronous with that in the field of human physiology. Up to now, there is no research on whether the decrease of people's mental entropy (such as strengthening study and constantly absorbing new knowledge) leads to the decrease of body entropy, but it is an indisputable fact that knowledgeable old people often live longer. When people retire, if they are not properly prepared psychologically, they are more likely to get old and get sick. This may prove that the increase of human entropy in the spiritual field is consistent with the increase of physiological entropy.
Do social organizations have the same process of aging and death as the human body? The answer is yes. Philip kotler, an American scholar, pointed out in Social Marketing that a social organization also has a process of birth, development, aging and death. When a society comes into being, new slogans, new ideals, new action plans and new grand goals can often win the broad support of the people. With the gradual expansion of social organizations, its internal structure has become more and more complex, and the chaotic factors in the organization have gradually increased. At this time, in order to safeguard the interests and survival of the organization, the organization must make great efforts to overcome the chaotic factors. At this time, the goal of the organization will become how to survive for a long time and gradually move away from the original goal. In fact, the chaos within the organization is the process of entropy accumulation. If the organization lacks the process of entropy reduction, the process of entropy increase is the inevitable fate. How do we reduce the entropy of the organization? Perhaps, the human body needs to sleep and wake up alternately, which can get some inspiration.
People need to eat, shit, sleep and have sex to maintain the entropy reduction process of human body and human species. So, how does the organization maintain the entropy reduction process?
