🛌 In ancient Egypt, people used round stones instead of pillows. This was due to the tradition of preserving the shape of the head after death, as they believed in the possibility of resurrection in the afterlife. Stone pillows were convenient for this purpose, as they did not deform the shape of the head. Later, in more developed societies, more comfortable and soft pillows appeared, but the tradition of using stone pillows was preserved in some religious circles. Nowadays, stone pillows are used as a decorative element and style in eco or minimalist interiors.

Vegetarians fart more than non-vegetarians. In 2021, Spanish scientists set out to examine the phenomenon that's always been presumed: plant-based diets cause people to fart more. The researchers concluded that people who follow a plant-based diet fart more and have larger stools than people following a standard Western diet (diet low in fruits and vegetables, and high in fat and sodium). The results revealed that those following a plant-based diet farted seven times more per day and had stools twice the size as those following a Western diet on average. Farting is a sign of a healthy diet and healthy colon, said the scientists.
