Xiaoming Quotes:
In addition to fluid intelligence and crystal intelligence, there is now a new intelligence model called WeChat intelligence and short video intelligence. The characteristic of this intelligence is that it attaches importance to thinking results, rather than thinking processes, or can only perform shallow brain processing, unable to think deeply, and calls the brain system 1 for work.
01 The bottom line of learning and practical psychology
The real reliable psychology is that all our conclusions must be based on the scientific achievements and scientific principles of human discovery and research. Many people learn psychology into narrow psychology ,
discuss problems very one-sided , and solve problems very casual and arbitrary , giving people the feeling that is not professional . Of course, in the end, it is impossible to let others trust .
trust relationship is based on professional , which is also the reason why everyone comes to the disciple class. Because the knowledge we have learned from us is obviously more professional than outside, this is the bottom line for learning .
So, today I will talk about immune system knowledge everyone must master it. In fact, this is also common sense, but it is difficult for everyone to combine their body with the knowledge in the biology textbook I learned before.
Our stress response, stress and emotions will have on immune system and what impact it will have, you must understand.
02 How to start the immune system?
First of all, human beings are a living body, and is not just our own . In fact, before we were born, and the mother exchanged various body fluids through the umbilical cord and amniotic fluid . We will be brought to our mother by various bacterial flora and shape our own bacterial flora environment .
So the first batch of bacteria obtained by each person's body, including virus , is actually obtained from the mother. Then I will slowly adjust the bacterial flora of through my personal genes.
Because has different genes in , we eat and drink differently, so each person's intestinal bacterial flora types are different. Our body will recognize and maintain a normal bacterial flora that is good for itself. Just like the identity ID, you can know whether this thing can exist in our body for a long time, and which ones must be removed.
body Classification and identification of "foreign objects" :
Classification and identification of "foreign objects"
Classification and death;
Classification and mutated, such as cancer cells;
Classification and third, foreign, without ID cards, are the pathogenic viruses and bacteria that we call foreign. After
is recognized, the body will start the immune response and drive away . Similarly, three different immune cells in the human body, , will perform the work.
The first type is lymphocytes with phagocytosis function , looking for the three types of "foreign objects" we mentioned above, and after finding them, they will enforce the law and swallow them directly.
The second type, B lymphocytes , it is not phagocytosis type. After it found the bad guy, it found that it could not finish it alone, so it began to copy itself and generate a policeman and antibody that could specifically fight against the bad guys.
Just like the picture of " Matrix ", B lymphocytes can copy a lot and generate antibodies. After the antibody is generated, you can slowly clean up the antigen that enters the body one-on-one.
The third type, T lymphocytes .Specialized in the production of a powerful special weapon that can kill foreign cells, this is a special policeman.
B cells and T cells work through the lymphatic system . Like blood circulation , lymph circulation also has a system and is connected to blood circulation.
In other words, as long as blood vessels can reach, these B cells and T cells will go anywhere, identify them everywhere, and they do their work all over the body.
and are combined with . There is a characteristic specifically targeting a certain type of virus and microorganism , specifically copying the problem targeting this bad guy. This is what produces antibody .
antibody is also called memory cell . It can be remembered and attacked directly when encountering this thing in the future. The time when antibodies exist in the body is uncertain.
is determined based on the function of antibody and the degree of variation of bacterial virus . Some may be a month, and some may even be possible for decades.
03 The current three types of enemies of the human body
After discovering penicillin and antibiotic , humans have a certain way to harm bacteria. There are some strange things in Chinese cuisine, such as stinky tofu and some fermented foods. The above is . Some bacterial groups have a functional effect that resist harmful bacteria in the human body. .
Although excessive use of antibiotics may also cause some bacteria to turn into super bacteria , and you are not afraid of any antibiotics. But so far, humans have basically solved the problem of bacteria. The remaining is mainly harmful to the following two types of :
(1) very fine and small metal particles . They cannot be digested and cannot be removed when they enter the body, and the harm is particularly great, such as pneumoconiosis, haze infection, etc. of coal miners.
Sometimes it exists in one place, and the human body needs to to attack and interfere with , and it will be wrapped in , resulting in some hyperplasia . It looks like the shells that are known to be wrapped in a scrap that comes in from outside and secretes some substances to form pearls.
Under normal circumstances, hyperplasia is not a big problem, but sometimes hyperplasia will change. Assuming that some vascular connections are generated, the immune system constantly secretes some chemicals for repair work here. These chemicals can easily cause normal cell mutations, which will form more serious nodules. Finally, evolved into tumor cancer cell .
(2) virus . Why are viruses more harmful than bacteria? Because a virus is not a complete life cell like a bacteria, it is a parasite and cannot survive independently. After entering the body, the virus will immediately parasitize into other cells.
parasitic harm is very high , and will cause inflammation . For example, if it parasitizes in heart cells, myocarditis will occur, and if it parasitizes in kidney cells, nephritis will occur.
people will fight with these virus parasitic cells. The result of the war is often three types of :
- wins , and the virus is eliminated;
- cannot win , and the person dies;
- compromises and incorporates the virus into our body's gene combination .
The genes of humans actually have many foreign biological genes , just like a wild animal domesticated by us . But this domestication comes at a cost, and it is often not something that one person can do. It requires the entire human being to be infected with a virus. Many people die, and some surviving people can live with it.
The most typical example is mitochondrial found in gene detection . It has strong typical cancer cell functions, and the efficiency of absorption, hijacking and energy conversion is particularly high, which is much higher than the various cell transformation capabilities of in our body.
Later, humans domesticated and adopted mitochondria to transform various energy in our bodies. Mitochondria sometimes induces apoptosis and cancer cells to function the same. Of course, mitochondria now induces human cell death, which is no longer harmful to humans.
But it is obvious that humans have not been able to solve their abilities like cancer cells, and they have not been successfully included. If humans can successfully incorporate , some people expect that infinite reproduction speed such as cancer cells will make people live longer.

Xiao Ming's quote:
Chaplin 's " Modern Times " and the Matrix both reflect the separation of people's body and spirit in the machine era, but Chaplin's silent movie is obviously simpler and better.
so, on the one hand. We chose not to talk about simple psychoanalysis . On the other hand, we strive to explain the deepest psychoanalysis simply and clearly. That's my goal.
