2. You pass about half a liter of gas per day.

This is enough hot air to fill a medium sized balloon every day.

3. Farts get their stinky odor from just 1% of the gas you release.



Ninety-nine percent of a fart is composed of odorless gases. It’s the infamous 1% that is typically sulfurous that give farts the odor they are known for.

4. Smelling farts may be healthy.

A recent study found that hydrogen sulfide, the gas that makes farts and rotten eggs smell particularly gross, might prevent mitochondrial damage. The study was talking about direct treatment of cells with hydrogen sulfide, and was in no way related to farting, but we’ll be using it as an excuse to let ‘em rip until someone tells us otherwise.


5. Women fart just as much as men.

The sphincter muscles help keep the anus closed.  When the gas comes out it causes vibrations and the tighter the sphincter the louder the fart.   If the sphincter is relaxed the toot will most likely be quite but if they are tight get ready to rumble!
