Self-help ✦ Penny’s Take
Why Zebras Don't Get Ulcers
Robert M. Sapolsky · 1994
88/100
👍 Worth It
Sapolsky pulls off something genuinely rare: a rigorous biology of stress that's also laugh-out-loud funny and immediately useful. The core insight — that chronic human worry does damage the body in ways a zebra's acute fear never does — is explained so clearly you'll never forget it. One of the best popular-science books written in the last thirty years.
