You probably fart more during a 24-hour period than you think you do. Even if you're holding in a fart from time to time as you go through your day, you can't consciously deny your gas while you're sleeping -- and when you total it all up, including your nocturnal gas-passing, you may fart an average of 14 times per day.

In fact, it's pretty normal for one person to pass between one and four pints of gas (about an eighth to a half a gallon) in the course of just one day -- and that means we're all passing somewhere between 13 to 21 farts per day [source: Kluger, The Merck Manual].
