A new study published in the New England Journal Of Medicine Tuesday reveals just how frequently men are farting when a woman leaves the room. The study reported that men are farting 97 out of every 100 times a woman gets up to go to another room, about 10% more often than most people thought. “We need to qualify the findings,” cautioned one of the co-authors of the study. “First of all, these are early findings. Second, we’re not talking about actual numbers of farts, or even the type of fart, but just whether or not there was a fart. Still, it’s a little troubling. I think most of us would have guessed the numbers would be much, much lower, maybe 70, 80% at most.”.
