There are many small details in life. We only know how to do it, but we don't know why. My mother often tells me to sleep on my side. I asked my mother why she slept on her side, but she couldn't explain it clearly. Now I finally understand after reading this book. Why do you sleep well on your side? Because if you sleep on your back, it is easy to dream, and you will feel very tired after waking up, which may even cause difficulty breathing. If you sleep on your stomach, on the one hand, it will oppress your heart, on the other hand, it will be easily blocked by pillows, which will also affect your breathing and make people feel uncomfortable. It can be seen how important it is to sleep correctly. We need a good body to study hard. It is said that health is the capital of revolution.
My mother always tells me to wash my hands with soap when eating. I wonder why I can't just wash my hands with water. This book also told me the answer, which made me suddenly realize that because the bacteria on my hands can't be washed off by water alone, it must be washed off with a substance called sodium stearate in soap to keep my hands clean.
This book also tells me a lot of things I don't know at ordinary times, which makes me healthier in my living habits. The knowledge contained in nature is incredible.
