That's over 100 people, for those of you not quick at maths. Over. One. Hundred.

Commenters were quick to weigh into the debate, with some questioning the effectiveness of the drains, and others just expressing pure horror.

"How are the six percent not spending all their time resolving drain issues?" one person questioned. "I could shower for 30 seconds and the plughole would be overwhelmed by my hair so HOW THE HELL are their plumbing systems coping with a turd?!"

"I want you to know this poll has deeply upset me," wrote another.

Most of us pee in the shower - one in three, in fact, according to the same study. But that is a whole lot more hygienic than number twos, and of course, easier to wash down the drain.

And call me crazy, but isn't pooing in the shower slightly... counterproductive?

So, we're sorry, but if you work in an office with at least a few dozen people, look around yourself. Someone there is a secret shower shitter. Who could it be?
