Why do we crave sugar we don't need? Fall for the wrong people? Lie awake worrying about things that haven't happened? Feel hollow on a perfectly good Sunday afternoon?

Because you are not, in any meaningful biological sense, a modern person. You are a hunter-gatherer in a glass tower, running ancient software that was finalized for a world that ended, on the calendar of our species, about a minute ago.

In *Designed to Feel*, Peter Burchardt offers a single, clarifying lens for the whole strange experience of being a human being today. Your emotions, every last one of them, were designed by evolution as a steering system: a precise arrangement of carrots and whips built to keep your ancestors' genes alive on the African savannah. Hunger, love, fear, jealousy, awe, shame, wanderlust, grief — none of them are random, and none of them are personal flaws. They are tools. You were just never handed the manual.

This book is the manual.

Across thirty-nine chapters, Burchardt traces the evolutionary origin of every important feeling you have, shows where each one misfires in modern life, and explains what to do about it. You will learn why happiness is a signal rather than a destination, why most romantic relationships drift around the eight-year mark, why nightmares are not omens, why social media is a trap your brain cannot defend against alone, why a short trip works as a small reset of the mind, and what life is genuinely for, once you understand the machinery that built you.

Written with the warmth of a father trying to give his sons the manual he was never handed, and the clarity of someone who has thought about little else for years, *Designed to Feel* is the book to read if you have ever finished a self-help book and felt that something in the explanation was missing. The missing piece is your evolutionary history. Once you see it, the rest of your life makes sense.

For readers of *Sapiens*, *The Moral Animal*, *Behave*, and *Why We Sleep*.
