This is a video from AsapSCIENCE explaining the science behind why people don't mind the smell of their own farts but are disgusted by other people's. Speak for yourself -- I don't even like my own. Probably because a lot of the times I accidentally shit myself. Also, it's easy to understand why people don't like other people's farts -- BECAUSE THEY CAME OUT OF SOMEONE ELSE'S @$$HOLE. I'd be disgusted by anything that came out of another person's butt, even if it was a fancy watch.
Keep going for the video.
Thanks AsapSCIENCE, now explain to me why other people's pee always tastes better than mine.
