The Reason Why Some Of Your Farts Smell Nastier Than Others
Obviously we're only talking to the guys here because everyone knows girls fart unicorn dust, but the heroes over at Thrillist took one for the team and asked an expert about why everyone's fluffs smell so different.
And not just person-to-person different, either; they wanted to know why your own flatulence is sometimes on the "barely noticed it" side of the scale, and other times heading straight for the "rotten eggs" end.
Turns out we have a lot of control over what comes out by taking care of what goes in.
"Smell odour is not bad, it's just a function of what you're eating and what your bacteria is doing inside your gastrointestinal tract," explained Dr Myron Brand, a gastroenterologist at Connecticut Gastroenterology Consultants.
"Everyone is different. Foul smell just means the carbohydrates you consume are being malnourished - it's fermented."
Just like the schoolyard rhyme goes, fiber-rich foods like beans, broccoli and sprouts mean plenty of gas, thanks to their wonderful gut bacteria-boosting abilities.
Protein is also to blame for some whiffy whoppers, apparently, so it's a wonder the gym doesn't smell worse than it already does.
Dr Brand added: "Some people are methane producers, and some people are hydrogen sulfide producers - which causes flatulence to smell like rotten egg.
"It's all a function of what you eat."
The main thing to take away from all of this, though, is that farting is a totally normal bodily function and the frequency and aroma will vary from person to person.
