I like it because it is written almost jargon-free and it’s a lot of fun, as the title indicates. As Sapolsky explains, when we worry or experience stress, our body turns on the same physiological responses that an animal's does. However, animals stop experiencing stress when the environmental emergency passes,  while we humans can worry for long times and thus produces the same physiological responses which, if chronic, can take a toll on our bodies and, if prolonged, can make us sick.
