Seven and a Half Lessons about the Brain(Barrett, Lisa Feldman)

 1. The human brain is amazing the more you learn about it.


Including your brain, which supervises the movements of over 600 muscles, balances various hormones, pumps 2,000 gallons of blood a day, regulates the energy of billions of brain cells, digests food, excretes waste, and fights disease, all without resting for about 72 years.

As the quote says, not only humans but also animals perform these functions, but humans additionally have many thoughts and actions, and their own rules and systems in various aspects such as creative, social, political, and scientific. In this way, it is very different from simple creatures, and I was able to learn more about how much the human brain does. With so much to do, it seems natural that we sleep. However, it is said that the brain does not rest even when we sleep. It continuously performs various tasks such as organizing memories from when you were awake, maintaining homeostasis of the body, and increasing immunity. Much about sleep has not yet been discovered, and much about the brain is still shrouded in mystery. If we know everything about the human brain, I wonder what life will be like after that.


2. In the end, everything depends on parenting.


You can't expect babies' brains to develop normally just by giving them food and water. You have to make eye contact with them, talk to them, and touch them to satisfy their social needs. If these needs are not met, the seeds of disease can be planted very, very early.

I once explained the following anecdote in a review I wrote after reading Carl Sagan's 'Cosmos'. A psychoanalyst named René Arpad Spitz (1887-1974) took care of abandoned children at a hospital. He provided the children with a clean environment and enough food, but the nurses did not talk to them, make eye contact, or hug them at all. Babies who were raised in hospitals for more than 4 months showed mental abnormalities. However, in a Mexican orphanage that I happened to visit, the children were said to be very healthy, even though they were unsanitary and provided insufficient food. It is said that women from the neighborhood visited the Mexican orphanage every day to play with the children, hug them, and sing to them. Additionally, a psychologist named Harry Harlow (1905-1981) conducted an experiment called attachment theory. He said that when monkeys were given surrogate mothers made of wire and surrogate mothers made of soft fabric, the monkeys followed and hugged the surrogate mother made of soft fabric more. In the end, what I think is true is that money is not everything. As a parent, you should never say to your child, “I have given you everything materially, so why can’t you do this (as much as the parents think)?” I think Korea in particular should not forget this. In the past, Korea was a very poor country. However, we are now abundant and no one around us is starving, but many issues are arising. Also, today’s young people are growing up in a very healthy and good environment. I think the role of parents is to always give their children attention and love (not material things).


3. Always have a mind of empathy.


When you try to see the other person's point of view and make a sincere effort, you can change your future predictions about people with different points of view.

We can see many people with opposing opinions in our lives. Because of anonymity, we can see this phenomenon even more severely on the Internet. Culturally and socially, sometimes it is right, but sometimes it is not. I think that if you respect each other's opinions and think about why the person said and thought that way rather than just saying that the opposing opinion is wrong, you will be able to understand the person. Of course, behavior that goes against the current culture or law is wrong. My wife does a good job of understanding the other person, so I reflect on myself a lot. There may be times when I don't know what I said or did, but my wife thinks from my point of view and explains why I thought that way, so I think about myself again. Thanks to that, I think I can think about it again and make better choices.

God delusion(Dawkins, Richard)

  1. It is the role of science to let us know the facts. Mystics rejoice in riddles and wish for them to remain mysterious. Scientists rejoice in riddles for a different reason: they give them something to do. mobile e-book: 320p In the past, humans practiced totemism, animism, and shamanism, offering sacrifices to improve the weather, performing rain rituals, or, as in the legend of mantou from the Romance of the Three Kingdoms where twenty head-shaped buns were offered to a river god to calm its waters, taking various measures to appease the wrath of gods through sacrifice. However, because science has developed, modern humans can now predict, to some extent, why weather phenomena like the rainy season and typhoons occur and where they will strike. We can even induce rain through artificial rain technology. Thus, when we are ignorant of the facts, things may seem miraculous and be seen as the work of gods, but once we know the facts, we can understand them. It seems that humani...

Parenting from the Inside Out(Daniel J. Siegel, Mary Hartzell)

  1. Let's Reflect on Ourselves "When you pay attention to your own experiences when you get angry at your child's behavior, you begin to realize how much your reactions have interfered with an ideal relationship with your children." (e-book p. 70) There are moments when I get particularly angry at a specific behavior of my child. I ask myself, "Why does this action make me so angry?" and "Why am I reacting so sensitively?" I reflect on whether I, too, received negative feedback for the same behavior in the past. By contemplating my anger and looking back at my past, I come to understand the root cause of my sensitivity to that particular action. I realize that my specific reactions are also responses stemming from past experiences. Therefore, to change my behavior, I must first acknowledge the origin of my reaction and then consider how to change. Through this process, I can restore my bond with my child and achieve deep self-reflection. My ingr...

Mindset: The New Psychology of Success(Carol S. Dweck)

  1. Life Is Yours "It is your chosen perspective that determines whether you can become the person you want to be and realize the value of your life." Mobile e-book: 27p Even when faced with the same situation, everyone reacts differently. I believe that life's outcomes are ultimately determined by our own choices. I think our current state is a result of our past choices. For instance, writing this book review is a consequence of my past decision to read the book. And my improving writing skills (though still lacking) are a combination of past writing experiences before starting the blog, plus the experience of writing more and more since starting the blog. This has led to the current result where I can now quickly write a book review in 1-2 hours (and marking important lines while reading helps reduce time spent on quotes). Similarly, your current state is a product of your accumulated past experiences, efforts, and trials and errors. No one is good from the start. Wha...
