Aunt Liu and I sat on the sofa in the hall on the first floor, and I was not polite, I asked Aunt Liu, "Aunt Liu, what is the name of the girl who jumped off the building and committed suicide." You know that. ”

Aunt Liu looked at me and said slowly, "Of course I know this." ”

"Then Aunt Liu, just tell me about it...

Aunt Liu said: "The girl who jumped off the building and committed suicide is called Liu Yao, a freshman who just entered the school this year, and I really want to study history. ”

"Oh... I nodded slightly, and said secretly in my heart: First-year freshmen who have just entered the school.

Aunt Liu said: "That Liu Yao's girl has a better personality. ”

"How do you know you have a good personality?"

Aunt Liu said to me: "Child, Aunt Liu, I have lived for many more years, I have never seen anyone, that child Liu Yao does not smile or speak when he sees anyone, and I have never seen Liu Yao and whose sins and whom." ”

"Oh. . . That's it.。。 ”

I touched my chin. asked Aunt Liu, "Aunt Liu, do you know if Liu Yao has a boyfriend or partner?" ”

Aunt Liu looked at me and smiled: "Liu Yao, that child is very well-behaved, basically he likes to play when he goes back to the dormitory, and he has never heard of a boyfriend." ”

"Oh. . . That's right. ”

Aunt Liu looked at me and said, "Liu Yao's kid occasionally comes to me to chat, and it's very good to me, an old man, to me. ”

"yes. . . Then it seems that Liu Yao should have a good relationship with you. ”

Aunt Liu said: "What's so bad about this." I'm the same for every girl who lives in Apartment Six. It's just that some girls are extroverted and like to communicate with people, and some girls are introverted and don't like to communicate with people. ”

"You're right."

I secretly said in my heart: "This Aunt Liu is really not simple, she must be very well educated." Otherwise, he wouldn't be so reasonable, and his emotional intelligence is also very high, and he gets along very well with the people around him. It seems that the people in the university, every simple person. ”

I looked at Aunt Liu, this Aunt Liu is very good at talking, and she doesn't hide anything, this is what I am most happy about.

"Aunt Liu, I really haven't been to the girls' dormitory, maybe it's different from us boys. I don't know what kind of playing time those girls usually like to play. ”

Aunt Liu looked at me and smiled, "What? Want to chase girls? ”

"Of course not. It's just that I'm curious. ”

Aunt Liu said: "Usually those girls chat on the Internet for a while, and some play some online games. Some girls like to dance and sing. There are also supernatural games that I like to play. ”

When I mention supernatural games, my eyes light up, because the boring time in college life is too long, after all, three years of middle school, three years of high school, I also came to the bitterness of student learning. I finally got through a university, and the pace of study was not as intense as in high school, so I naturally began to relax.

In fact, if you take a closer look at college life, you can divide it into three kinds of people: the first type of people is to play online games every day, and play online games all day long. This is mainly the best way to play time. There are just too many of them. The second is to engage in objects, and every day I wonder which beauty to find? And girls are thinking about what handsome guys are looking for, although there are not many such people, but there are also a lot. The third type of person is to bury his head in reading, attend classes every day, and return to the dormitory to read books after class. Such people can be said to be few and far between, but not none, in university life.

But no matter what kind of people they are, it is inevitable to play games collectively in college life. In particular, there are some people who do not believe in evil spirits, and they especially like to study ghosts and gods. In fact, research is not necessarily about believing, it is just about satisfying one's curiosity. After all, no one in this world has really seen ghosts, and even if anyone says that they have seen ghosts, in the end, they will definitely find that they are just fooling people and achieving some kind of goal.

So over time, there are two more traditions in university life. The first is to tell ghost stories, as long as someone in the school dies, there will be some people who will probe and get entangled with evil ghosts, in fact, the reason is very simple, and it is not so complicated. It's nothing more than a false rumor that has changed the original process. The second is the supernatural game. In college life, the supernatural game is to the pen fairy, the disc fairy. What bloody Mary, and other supernatural games are popular on college campuses. Although the university tutors teach the college students, the teachers can't control the class.

I asked Aunt Liu, "Then do you know that Liu Yao likes to play supernatural games?" ”

Aunt Liu said: "I should like to play. ”

"What do you mean by should?"

Aunt Liu said: "Once, Liu Yao and her bedroom played some supernatural game at night, and they almost burned the sheets. I also went up to the fourth floor to see... ”

"Oh. . . That's it... ”

I touched my chin and said secretly in my heart: It seems that this Liu Yao is the same as ordinary people, not only has a cheerful personality, but also should be a good person, and occasionally likes to play some supernatural games. According to common sense, even if something happens to such a person, he will tell his girlfriend, and even if he is unhappy, he will not commit suicide.

Because I've done a lot of research, there have been people who have studied the phenomenon of suicide in depth. Camus once said that there is only one really serious philosophical problem, and that is suicide. But in fact, this serious matter is still a worrying social phenomenon. In the United States, about 100 people commit suicide every day, and suicide is the 10th leading cause of individual death. In China, 290,000 people die by suicide every year, and 2 million people attempt suicide, and suicide is the leading cause of death among young people. Yes, what could be more suffocating than the abandonment of life? In addition to these abstract statistics, there are many well-known celebrities who also died by suicide: Vincent. Van Gogh, Marilyn. Monroe, Mayakovsky, Yasunari Kawabata, Hemingway, Sanmao, Gu Cheng, Haizi, Leslie Cheung, Ruan Lingyu, Weng Meiling. Suicide, at least in the eyes of many, is a puzzling affair. However, evolutionary psychologist Dennis . Morality. As early as the eighties of the twentieth century, Catanzaro proposed a shocking theory to analyze the suicidal psychology of human beings from a biological point of view. Catanzaro was teaching at the Department of Psychology at McMaster University in Canada. This was risky, because the study of human behavior from a biological point of view was a controversial undertaking at the time. You know, biologist Edward Wilson had been harshly criticized by his colleagues at Harvard University for his sociobiology claims five years earlier, and some people had personally attacked him during his lectures. Suicide, as a complex human behavior, is a reserved place for social science; They won't be easily touched. Not surprisingly, Catanzaro's article sparked criticism of him. However, in 1991, Catanzaro published a new paper in the journal Habitology and Sociobiology, which explicitly proposed the adaptor theory of suicide. According to Catanzaro, self-preservation is a powerful biological instinct, but this biological instinct is flawed by design. To put it simply, he sees suicide as an adaptive behavior in some cases. Adaptation here needs to be understood from the perspective of evolutionary biology. According to the theory of sociobiologist Hamilton, an individual's fitness is divided into two parts: the first part is direct fitness, that is, the fitness brought about by the transmission of genes by oneself; The second part is indirect fitness, which is the fitness brought about by the indirect transmission of one's own genes through relatives. These two parts add up to the overall fitness of the individual. In social animals, there is a mutual influence between the two fitness, which can be positive or negative. Imagine an ancient scenario where you are bedridden for a long time, your family needs to be around to take care of you constantly, your mother doesn't even have time to gather food, your father has been out hunting for a week, and your younger siblings need food to satisfy their hunger, but the limited food needs to be left for you. Your own future reproductive expectations are low, but your family members who carry some of your genes have high reproductive expectations, but your presence is a heavy burden on their successful reproduction. If this burden is removed, your direct fitness will be reduced, but your indirect fitness may benefit because you will have no negative impact on your family's reproductive success, and you may still have more offspring overall. - Although not through a direct path of their own. To summarize Catanzaro's point of view, he argues that suicide is a trick devised by natural selection, a trick to keep the car in charge. Through the self-destruction of individuals, they are more efficient in transmitting genes, in which case the suicide mechanism may be preserved by natural selection. Moreover, Catanzaro also argues that suicide requires meeting certain intellectual thresholds, because the activation of suicide mechanisms requires subconsciously weighing the pros and cons of suicide, and individuals with high IQs are more likely to do so. In addition, if the suicidality mechanism has some kind of adaptive advantage, then this adaptive advantage should have some genetic basis; In other words, suicide should have some hereditary nature. It is important to come up with a theory that can justify itself, but it is more important to test whether the theory is reliable or not, and to test the hypotheses based on it. So, is there any evidence for Catanzaro's suicide theory? There are at least three aspects of evidence consistent with Catanzaro's theory. Martin Volacek from the University of Vienna conducted a systematic study of the relationship between suicide and IQ. The results show that suicide risk is indeed closely related to IQ. For example, a follow-up study found that gifted children with an IQ of 151 were four times more likely to commit suicide than the average child. High-IQ people, including novelists, writers, playwrights, and poets, are also far more likely to die by suicide than the general population. This relationship also applies to certain special human beings: people with schizophrenia who die by suicide have higher IQs than their counterparts at the end of their lives. Investigations from Italy, Austria and Belarus all confirmed Volacek's conjecture that people with high IQs were more likely to die by suicide. Research from behavioral genetics provides some support for the heritability of suicide. A national survey in Denmark found a higher association of suicide risk between siblings than between siblings. Swedish researchers also found that the closer the kinship between two individuals, the higher the risk of suicide was correlated between the two individuals: identical twins were higher than fraternal twins, fraternal twins were higher than cousins, and cousins were higher than strangers. Catanzaro and Brown of Pacific Lutheran University, through their own research, directly tested the adaptive theory of suicide: when an individual's ability or expectation to achieve overall fitness decreases, an individual's suicidal ideation increases. As early as 1991, Catanzaro conducted a survey of various groups, including normal people, homosexuals and the mentally ill, and found that the most closely associated factor with suicidal ideation was the influence of the individual on the family. Once they feel that they have become a burden to their families, they are more likely to have suicidal ideation. People who feel that they are contributing to their family are less likely to have suicidal ideation. Brown et al.'s study also found that individuals were more likely to have suicidal ideation when they felt they were a burden to their families. However, the relationship between the two is influenced by health, the quality of the romantic relationship, and the age of the mother. When their own health is poor, romantic relationships are poor, and mothers are younger, people who perceive themselves as a burden to the family have the strongest suicidal ideation. Poor health and poor romantic relationships mean that individuals have a lower reproductive potential in the future, and if they become a burden on their families at this time, it means that they will also reduce the reproductive potential of their family members, thus worsening their overall fitness, so suicidal ideation is more likely to occur. A young mother means that the reproductive potential of the family is higher, which is a burden to the family, which will also reduce her overall fitness - a mother who may have more offspring may spend a considerable amount of resources on herself because she has to take care of herself who has become a burden on the family, and this "waste" will eventually bring a cost to the transmission of her own genes. Camus as a philosopher is profound, because suicide is serious. Suicide, though, is more of a serious biological act than just a philosophical contemplation. Catanzaro's interpretation of suicide from a biological perspective, and the testing of this theory by other researchers in their respective fields, preliminarily support the idea that suicide has a biological basis. Giving everyone a better future and making everyone a positive force in the family may be the solution to radically reducing suicide.

Aunt Liu saw that I didn't speak for a long time, and Aunt Liu asked me, "Child." What do you think? ”

"No. I didn't think about anything. I'm just curious.,What would such a good girl do to commit suicide.。。 ”

Aunt Liu sighed and said slowly: "Every family has a scripture that is difficult to read. . . ”

"Aunt Liu, it seems that you know what troubles Liu Yao has encountered?"

Aunt Liu said, "I don't know." It's just that everyone has their own things, life is like this, unsatisfactory things nine times out of ten, sometimes you can't see it just by looking at the surface. ”

Listening to Aunt Liu say this, I secretly gave a thumbs up in my heart, high. Only in being high.。

I unconsciously lit a cigarette and wondered where I should start investigating.

I looked at Aunt Liu and said, "Aunt Liu, you don't smoke." ”

Aunt Liu said: "I don't smoke. ”

I laughed, "Hehe. I'm sick for the rest of the year, and sometimes when I think about things, I smoke unconsciously. ”

Aunt Liu said: "Originally, smoking was not allowed in the dormitory. But now some girls, you say you don't let her smoke, or smoke secretly, and you don't care. ”

"yes. . . Today's children are more skinny. ”

Aunt Liu said: "I don't know what is good about smoking this cigarette, not to mention whether it is expensive or not, it is also harmful to the body, how many people end up with terminal illness because of smoking." ”

I smiled at Aunt Liu and said, "No way." When I was a child, I watched others smoke handsome, and as a boy, I also smoked, who knew that I would be addicted to it. I can't quit anything. ”

After saying that, I smiled awkwardly to myself.

Aunt Liu looked at me and smiled and said, "Look at you, this kid is not bad." Otherwise, there won't be anything to do to investigate this.。。 Now, this apartment No. 6, I don't know what to steam. Now the girls have moved away. Basically, there are not many girls living in this apartment No. 6 anymore. ”

"Aunt Liu! I've heard that apartment No. 6 is haunted, and there is a girl's laughter every night, and crying or something? Is there such a thing? ”

When asked this, Aunt Liu looked at me and said, "Hey. Maybe I'm old. I couldn't hear anything, and if it weren't for the girls knocking on my door one night, I wouldn't have heard any laughter or crying. ”

"Is there any laughter or crying?"

Aunt Liu said: "There was no crying at that time, but one night I did faintly hear laughter." ”

"You do laugh."

Aunt Liu said: "I'm so old, and I've experienced some things, what gods, ghosts, I never believed, but from that day on, I also felt a little strange. ”

"What's so weird."

Aunt Liu said slowly: "What do you say about the laughter." It's not laughter, it's not. I still think about it when I listen carefully, but I just can't find where the sound is, sometimes it feels like it's eavesdropping, sometimes it feels like it's in the wall... ”

"It's scary."

Aunt Liu said, "Isn't it? ”

"Aunt Liu! There are still a few girls living here in Apartment No. 6. ”

Aunt Liu blinked, as if she was trying to think.

Aunt Liu thought for a long time before she said slowly: "I think there are only four girls left." ”

"There are four girls left."

Aunt Liu said, "Yes." These four girls are now in a room, some because they don't have the money to rent a house outside, and some because they have the guts, and they like to see what kind of ghosts are doing when they have nothing to do. So these four girls stayed. ”

"I live on the next floor, Aunt Liu."

Aunt Liu said: "On the fourth floor, bedroom 402 is separated from bedroom 403. ”

I nodded slightly, I remember who said that. The girl who committed suicide by jumping off the building lives in the 403 dormitory, and I know that I should know about it by now. It's time to take a good look at the environment on the fourth floor and see if there's anything strange about each floor.

I said to Aunt Liu, "Aunt Liu." I want to go upstairs and check it out. ”

Aunt Liu said to me, "Yes." If you want to go up and have a look, your aunt will accompany you to go up and have a look. ”

"That's good. I want to take a closer look at each floor. If I could, I would stay one night to see what was so strange about this apartment number six. ”

Aunt Liu said slowly: "That's it. . . But there were four girls on the fourth floor. ”

"Don't worry, I won't bother those four girls."

Aunt Liu said slowly: "It's best not to affect girls." After all, there is a difference between men and women. ”

I laughed and said, "I know this... ”
