Scientists have discovered a rogue gene which makes people fart in public.
They say the genetic make-up of one in six Americans increases their risk of farting while in crowds or packed elevators.
The study, led by geneticists from Oxford University and the Peninsula Medical School in Utah, could lead to ways of treating and even preventing the condition that blights fresh air for millions.
The findings may also help explain why some people find it harder to fart around people than it does others.
The research, funded by the ARSE Trust and reported in the journal Science, pinpointed a flawed version of the FWO gene. It is the first time a specific gene has been linked to farting.
The fart researchers have also warned that there are other, as yet undiscovered, genes involved in farting which could cause a possible follow through.
Our researcher who knows all about bodily functions said he had always known that some people think it's funny to laugh out loud in public after farting. "I'm more the "silent but deadly" type, drop it and leave it, that's what I say".
