Why Zebras Don’t Get Ulcers

Think about the zebra fighting for life on the Serengeti plains. Being chased by lions is pretty stressful. Despite this, though, zebras don’t get stress ulcers. And human beings, despite never being chased by lions (or at least very rarely), do. Why is this? With Why Don’t Zebras Get Ulcers, Robert M. Sapolsky sets out to explain why prolonged stress is so human an issue. More importantly, he explains why prolonged stress is so unhealthy and what you can do to fight it. From biology to culture, Robert M. Sapolsky covers every angle of stress in modern society.
