This book is named Surrounded by Idiots: The Theory of Human Behaviour and How to Effectively Communicate. It was written by Thomas Ericson. In this part of the book, they are explaining the different perspectives of the different cultures and helping you understand how different we are. And the meaning of the four humors.
Humoral pathology, or the theory of the four humours or four bodily fluids, has to do with the four temperaments. According to Hippocrates, our temperament is the fundamental way we react. It’s our behavior or our natural frame of mind. Our temperament controls our behavior. Hippocrates believed that your health is good when the four humors—blood, yellow bile, black bile, and phlegm—are in balance. When we vomit, cough, or sweat, for example, the body is trying to rid itself of one or more of these substances. The word chloe comes from Greek and means “yellow bile.” Therefore, a choleric person is controlled by yellow bile or the liver. Fiery and temperamental, choleric people sometimes frighten those around them with their powerful ways. “Choleric” can be translated as “hot-blooded.”

I choose this part because it was fascinating how the humors are related to body fluids. This paragraph is really important because it teaches you how does the four humors work.
