It's Saturday, March 7th, 2026 — and before you do anything else today, we're talking about something you've been doing since before you could walk. Laughter. Not the polite kind. The real kind. The kind that makes your stomach hurt and your eyes water and makes everyone around you start laughing too without even knowing why.

Turns out science has a lot to say about that.

Today we're looking at four peer-reviewed studies that together tell one remarkable story: laughter isn't just a reaction. It's one of the oldest, most powerful biological tools humans have — for bonding, for healing, and for staying alive longer.
