Toilet paper in the bathroom, always leave it like this: the reason is absurd but it saves your life

Today everyone wonders how, when, to use and place toilet paper. Once upon a time, for example in the Middle Ages, there was no toilet paper.

There were those who used a scraping stick and those who used hay, stones, sand, hemp, wool, corn cobs, husks, fruit peels, ferns, sponges or shells or even ceramic scrap.
