In this chapter, we learn that the brain is the "command center" of the body, and that a person who takes control of the brain will be accepted by the body. This means that the person must be able to control the body's physical functions, such as breathing, heartbeat, and blood pressure. The person who controls the body must also control the brain's emotional functions, which include the ability to communicate with the rest of the world. In other words, the person with the most emotional control over the body is the one with the best chance of winning the game. This is why, in order to win the game, the two men must work together.
