Imagine how much more pleasant life would be if flatulence had a nice aroma, rather than an odor. A scent nearly universally appreciated, like baking bread or vanilla (or some otherwise unknown but very pleasing fragrance).
No, they’d be disgusting because basically smelling a fart is inhaling vaporized shit. Shit can be green, and most people like green, but they’re not usually so fond of diarrhea green.
Yeah, but perfumes are nowhere near universally accepted as smelling nice. On the other hand, I have never heard anyone fuss about the smell of cinnamon rolls in the oven.
mmm
Baking bread and vanilla smell good because they are associated with positive things. Farts smell bad because we are designed to recoil from the smells of potentially disease bearing things, like rotting flesh or feces.
So if farts smelled like baking bread, it’d be most likely that we’d start hating the smell of baking bread, and bakeries would be considered noxious industries.
I’d say that, since the instinctive dislike of all things scatological (well, for most people) was a result of many eons of natural selection, even if it smelled “like” lilacs we would come to loathe it anyway.
I once read an essay by Benjamin Franklin where he suggested that someone come up with an “X-Prize,” as it were, to encourage the development of a pill that would make farts smell pleasant.
So, what if they smelled nice? They probably do smell nice to the very few people occasionally born with a mutation that makes them like the smell, and those people are less likely to have healthy lives and procreate, and it’s no fun to be them. That’s what if.
