Описание: Right now, someone near you is about to yawn — and within seconds, you're going to yawn too. You'll tell yourself it's just tiredness. It's not. The real reason is far older and far stranger than anything happening in your lungs.

You'll learn what real researchers found when they studied contagious yawning in humans, in children, and even in wolves — and why that "ancient signal" is still firing every time you catch someone else's yawn.
