When playing for money in the Sich, there was a tradition to take off your shirts so that no one could cheat by hiding cards in their sleeves. Authors: Jimmy Wales, Larry Sanger Random interesting fact from the Great Encyclopedia: Why do we need salt? The human body contains about 47 liters of water. It turns out that many of our organs contain a surprising amount of water. For example, muscles are 75% water, the liver is 70%, the brain is 79% and the kidneys are 83%! But this body fluid is not pure water. It's actually saline. Why is it so? According to one scientific theory, all animals living on earth, including humans, are the descendants of organisms that appeared and lived in the sea. The body fluid of these creatures was sea water. By moving to land, they retained sea water as their body fluid. But the earth is not able to provide enough salt in its natural form. Since salt dissolves in water, a significant part of the salt from the soil is washed out with rainwater into rivers, seas and oceans. As a result, plants growing on the ground do not contain enough salt. This is why plant-eating animals need salt. The body loses a certain amount of fluid containing salt every day, and plant foods do not replenish it. Animals that eat other animals do not need additional salt. They get the salt they need from the body of their victims. This also applies to humans. For example, the Eskimos eat mainly meat, so their need for salt is very small. People living far from the sea have an increased need for salt. In ancient Mexico, salt was so highly valued that there was even a god of salt. In Europe, in ancient times, people were often paid with salt for the work they did. The English word "salary" (salary) comes from "salt" (salt). In the human body, salt accumulates mainly on the skin. If a person eats unsalted food, the blood loses its salt in various ways. Therefore, the skin must transfer its stores of salt into the blood in order to keep its concentration in the blood constant. This often has a positive effect on skin diseases. That is why, for some diseases, doctors often prescribe salt-free diets. Salt is removed from the body mainly by the kidneys. If a person's kidneys are sick, he is prescribed a low-salt diet so as not to overload them.
