Although the question of why farts smell seems mundane, very few people actually know the answer. If you don’t care yourself, you may want to know the actual answer to avoid an awkward moment when your children one day ask you, Why do farts smell?
The reason we fart is to dispose of gases that are built up within our intestines through the regular course of a day. Much of this gas is simply oxygen that everybody unavoidably swallows. But of course, there is more to it than that, or else you wouldn’t get the trademark “stink” associated with this most basic of bodily functions.
Every human being has bacteria living inside them. This bacteria assists with the breakdown of foods to allow the nutrients to be absorbed by your body. There’s of course, an unintended side effect to these little helpers and their careful assistance: additional gases.
Much of the smell accompanied by your farts is due to the sulfur rich compounds being broken down by these bacteria. For this reason, a person who’s diet is heavy in sulfurous foods, such as meat or eggs, will tend to have a stronger odor when farting.
The good news is, you’re not the only one. The average person farts about 12-14 times per day. Even the lady-folk who tend to deny it. The only real difference is that some people are prouder than others about the event. Even the best “holders” are incapable of preventing 100% of all farts, they just sneak out when they’re sleeping, instead.
An important consideration when trying to hide the smell of your farts: when running away from the smell, your movement can literally drag it along with you. And for those in cold climates, you can SEE farts. You can see them the same way you can see your breath. Warm moisture is a terrible, terrible give-away.
