Twenty One***********

This book is very interesting! The author Takeo Sakai is like a guide, taking us to explore the "eliminate" organs of the human body, which opened my eyes. His explanation is very easy to understand, I really like it. And the book also mentions some annoying characters, such as wisdom teeth, which cause me terrible pain every time they become inflamed. But this also made me understand my body better. It turns out that these organs have their own stories. All in all, this is a very interesting popular science book and worth reading!
