Nausea in the car, can shapes, genetic variation, and animal decomposition

The chapter explores why nausea is more common in the back of a car due to conflicting signals from the body's orientation systems. It also discusses the design logic of conical cans for efficient transportation and the genetic variations affecting how individuals perceive certain tastes. The conversation shifts to the process of animal decomposition, including the role of scavengers and the carbon and nitrogen cycle.
