A Brief History of the Human Body: Your Body Is 3 Billion Years Old

Thanks to Tomato, I am grateful to the author for allowing me to encounter this book in my middle age. I started to pay attention to the field of health care. I was lucky to come across this book. I believe that the books we read are inspired by our personal magnetic field. After reading this book, one of my biggest feelings is that all our medical progress comes from those adventurous souls and the spirit of exploration of physical diseases. I am grateful to those scientists and medical workers who have made outstanding contributions to defeating diseases. Their efforts have given us a basic understanding of ourselves, cells, and bacteria. Another personal experience is that we humans are very small, very small, so we cannot be arrogant. I cannot think that I am at the top of the entire food chain and do whatever I want. There are existences in this world that are smarter and older than us. We ourselves have many unsolved mysteries. We must be humble, coexist with other species, and find a path more suitable for our own survival.

People often say that if you know yourself and the enemy, you will never be in danger, but isn't your body the most important and critical part of yourself? In any case, read this book. It cannot be said to help you win 100% success in life. At least once you accept the knowledge in it, it will guide you throughout your life like a master. And it's not the kind of babbling that is calmly predicting, but some are magical smiles... It says that when you still don't know why, don't go around and listen to nonsense → It is necessary and inevitable for God to keep some secrets! A good book, a thousand out of ten good books. Mantras plus wonderful narration, knowledge empowers and resolves doubts. Of course, the human body is more than three billion years old, so it is dense and profound, and so is its brief history. Good book. I hope that Chinese scholars, professors, and academicians will also write works like this to present to readers with an objective attitude, detailed evidence, easy-to-understand narratives, and rich content. Of course, readers must be calm and patient. If you just want to find some fun and excitement, then...

A very good popular science reading, providing a comprehensive understanding of various organs and tissues of the human body. At least once you understand it, you will not be fooled, treat it in time, and prevent over-medical treatment. The most prudent choice for human beings seems to be a balanced and moderate diet. Simply put, eating more vegetables, especially those rich in fiber, is choosing a way of death when choosing a lifestyle. Treat baldness, asthma, sleep, yawning, digestion, burping, farting and many other daily phenomena correctly. Every cell with a nucleus has two copies of DNA, and DNA exists for one purpose only - to create more DNA. The powerful DNA has existed for 3 billion years, and the Y chromosome will disappear in 4.6 Million years. The Y chromosome is a strange little dwarf. It has only about 70 genes; other chromosomes have as many as 2,000 or more genes. For 160 million years, the Y chromosome has been shrinking. It is estimated that at its current rate of deterioration[7], it will completely disappear in another 4.6 Million years. This does not mean that men will disappear in 4.6 Million years. The genes that determine sex characteristics may be transferred to another chromosome, and sex may no longer matter.

Everyone is a small universe, and we really know too little about our own bodies. After reading this book, I realized that Western clinical medicine is really an empirical discipline. Every seemingly small conclusion drawn is based on the observation and analysis of countless life tragedies and death cases.

This is a very interesting book. It not only explains the knowledge of the human body from the microscopic aspect of elemental composition, but also tells the birth, aging, illness and death of a human body from the perspective of life span and diseases, helping readers understand the structure of the human body. It is rich in knowledge and full of interest. After watching it, I was in awe of life. It is a great thing that every organ in our body, and even every cell, can exist and operate well. And so many amazing miracles make up a person like us. Just living healthy is already a miracle.

I came to take a look out of curiosity, and I was unexpectedly interested.

A very exciting book about human medicine. I learned about the internal organs of the human body and related knowledge about Western medical pathology. If I have time, I will read it a few times to consolidate this knowledge. 😄

I really don't know much about my body, even though it's 3 billion years old. It turns out that I am the only animal with a chin, and I am also the only animal that sheds tears because of emotion. It turns out that it is because I have retained the memory of sleeping in a tree, so I will not fall off when I sleep on the bed. And, "Thin people have more gut microbes than fat people. Thin people have underfed microbes, which at least partially explains why they're so thin." That's why I'm fat, huh.

"Brain and sky, one can easily contain the other", we are part of the universe, and the universe is within us. Human beings have been constantly exploring themselves and the universe. "A Brief History of the Human Body" comprehensively introduces the revealed contents of the body - "a universe composed of 37.2 Trillion cells". It makes people marvel at the magic of life, but also regrets the inevitable death of life. No matter what, we have all received the precious gift of life, enjoy life! !

The birth of life is an extremely remarkable event, and the continuation of human civilization is more like a legend in the biological world. This book can be called an encyclopedia-style explanation book. From genes to cells to organs, it tells us the mystery of this mysterious instrument of the human body in all aspects. For example, all the components of the genome have one obsessive purpose: to keep your bloodline alive. In the 3 billion years since the beginning of life, your personal bloodline has never been interrupted, and humans have been continuously derived through genes.

This book is definitely worth reading for everyone, especially the wonders of body and soul that are worth pondering.

The immune system is big, a little messy, and spread all over the body. Many things we think of as unrelated to immunity fall into this category, such as earwax, skin, and tears. Any invader that gets past these external defenses (and only relatively few do) is quickly confronted by hordes of immune cells pouring out of the lymph nodes, bone marrow, spleen, thymus, and other parts of the body. A lot of chemicals are involved. If you want to understand the immune system, you need to understand antibodies, lymphocytes, cytokines, chemokines, histamine, neutrophils, B cells, T cells, NK cells...

The content is very exciting, and it is readable and easy to read without any sloppiness. Some of the examples of deeds given in the article make people feel unsatisfied and reflect for a long time. In particular, there is a part of the article that uses the current problems in the United States to illustrate the truth, which is amazing.

The biggest feeling after reading this is that there are many things that no one knows...

I especially like the author's explanations of some physical phenomena, such as why we don't fall out of bed while sleeping, and why human childbirth is so painful. The content in the book not only helps me understand my body better, but also gives me a deeper understanding of the wonders of life. It's perfect for reading with your children, learning and exploring at the same time!

This book introduces a lot of knowledge related to the human body, as well as the discoveries and advances in medicine over the years, and also triggers thinking about daily life. If you can keep reading, it will indeed trigger a lot of thinking.

It is a book that makes you feel shocked while reading, and makes your eyes want to pee. It popularizes various knowledge and physiological phenomena of the human body. We live with our bodies day and night, but we feel mysterious and unfamiliar with them. It turns out that our bodies are so delicate. It is both interesting and meaningful science. It is like a love letter from the body to you. Even if you don't have a high-paying job, don't have a glamorous life, are not recognized and understood by others, and look so ordinary, when you can't find the meaning, think about the billions of cells in your body. They are constantly fighting for you and loving you hard. You are all the meaning to them. Eat healthy food, do moderate exercise, go to bed early and don't stay up late, maintain a happy mood, really love yourself and your body, and don't let down their efforts. It took 3 billion years to create you now. Your existence itself is the most romantic miracle in the universe.

Am I the only one who came to read it out of curiosity as a junior high school student? Nice

This book made me cherish my life

I learned a lot about the human body. It's really amazing that people can survive. Every part of the body is so powerful. In many cases, instead of using others as role models, it is better to learn from your own organs and complete your tasks diligently and persistently [Cool]

"A Brief History of the Human Body" tells the story of the evolution of the human body from three billion years ago to the present, from apes and reptiles to humans who can now walk upright. The brain's conception is constantly changing, and the limbs are constantly coordinated. We have experienced constant birth, old age, illness and death. While lamenting the surprise of our own birth, we also fantasize about the sorrow of our children and old age. We are a member of the universe. We lament the rapid changes of the years, and experience the beauty of various surprising moments, enjoying the beauty and brevity of life.

Understand the magic of human body operation and the selflessness and greatness of life. It will make people feel that every cell is running hard for us during the reading process, which is very touching. In addition, I see that our daily routine and those ordinary ordinary moments are actually miracles day after day!

A very good book, my understanding of the body has improved a lot.

It's a very interesting book. It turns out that we still have so many ways to go in our exploration of the human body. There are so many heroic stories and so many tragic stories that happened in medical treatment. Being alive is already the result of your body's hard work. Be grateful to your body.

Every medical progress and development is not accidental, but inevitable for the development of human curiosity and exploration.

There are so many problems that people cannot understand, and life is so amazing. How sure is it that it only takes 100 muscles to make someone stand up? Eat less processed and sugary foods, eat smaller portions, and exercise more. How authoritative is it to extend life?

The information is substantial and complete, helping readers understand the structure of the human body and expand medical knowledge.

A very interesting book

Learned a lot of knowledge.

Life is full of miracles, and most people have some common sense about the human body, but this book is a systematic and comprehensive explanation and is recommended reading.
