I was also curious about Bill Bryson's other books, which are famous for their various travelogues, but I decided to read "The Body" first. This was largely due to the fact that the members of the group had become interested in health.

Provocatively, the title of the first chapter is "How to Make a Human." Bryson's middle school teacher (probably a science teacher) said that you could go to a hardware store with about $5 to buy the chemicals needed to make a human. How many science teachers in our country would explain it this way? I wondered this as I read the book with a wild mind. Bryson's biggest strength was that he was easy to read. How he could break down the complex functions of the human body, which are treated as separate fields in academia: anatomy and physiology... I even wondered if it wasn't more important who wrote it than what they wrote. Thanks to him, I was able to accept the unfamiliar subject of the "human body," even though it was my own.

The part I was most curious about before reading the book was the digestive system, nerves and pain, and the immune system. I wanted to know more about the areas I thought were weak. But as I read the book, I realized that it wouldn't do to just know about certain areas. All the seemingly separate areas have to work together to maintain the body, that is, to survive.

Of course, our bodies are still in the process of evolution, so there are many imperfections, and Bryson reminds us of this. He also reminded us that our bodies are constantly striving to be as functional as possible. Our bodies are doing so much for us, it's almost strange that we're not sick despite being exposed to so many diseases. Zablonsky wrote: "Losing most of our body hair and gaining the ability to dissipate excess body heat through sweat glands contributed to the massive increase in the brain, the most temperature-sensitive organ." In other words, sweat has greatly contributed to our intelligence. (From the text) I was surprised to learn that even sweating played a major role in our human evolution. I feel like I've opened my eyes to the body anew while reading the book. I wanted to read more books about the body and disease, starting with this one. Of course, I'm worried that it won't be as easy and fun to explain as Bryson's, but...
