Australia's national science agency spent three months asking people to tap a button on their phone every time they passed gas. The app was called Chart Your Fart. More than 19,000 people consented to take part, 6,416 produced usable data, and together they logged 360,192 individual events.
The headline number is the one nobody expected. The median participant passed gas 3.8 times a day. That sits below the range printed in nutrition textbooks and well under what U.S. federal health information tells the public is typical.
