Legs are a part of the human body, without which it is very difficult to lead a full life. They need to be given a lot of attention so that the legs serve us faithfully. Interesting facts about the health of the legs will help you correctly navigate how to take care of them.

Interesting facts about legs

A person walks quite a lot – he is capable of taking more than 10 thousand steps per day.

More than a quarter of the bones in the entire body are found in the legs.

According to statistics, a woman walks 5 km more than a representative of the stronger sex (data on average per day)

There are many more sweat glands on the feet than on other parts of the body. There are more than 250 thousand of them on both feet.

It is not surprising that a person can sweat a lot: the feet alone can produce up to one fifth of a liter of sweat per day – 400 milliliters.

Feet can exert a lot of pressure on the surface on which a person walks or runs. When we run, our foot presses on the ground 4 times more than our own weight.

The first shoes we put on our feet were more than 5 million years ago. They were, of course, leather, and were made from the skin of mammal predators.

It is not surprising that 90% of women develop calluses and corns: for the sake of beautiful shoes, they are capable of buying a pair that is too tight. For men, the comfort of shoes is the most important thing, not their beauty. In order to buy shoes and not suffer with them later, it is important to try them on in the afternoon, when the foot is already tired and has increased in size a little (swollen).

Foot size increases faster during pregnancy, during the period of active growth (from 13 to 19 years), and during the period of warm summer rains.

Shoes were not always divided into left and right. The Greeks were the first to introduce the system of right and left shoes (sandals).

How to calculate your own foot size?

Foot size began to be calculated in England by the size of the grain. The measure of shoe length was introduced by King Edward II. He counted how many grains with a diameter of 0.84 cm fit on the length of the foot. One grain - one size. This is how shoe sizes began to be calculated in the world.

The owner of the world's largest foot is Matthew McGrory. His foot is size 65. And the smallest foot in the world belongs to a woman - her foot is equal to 30 grains, that is, it is size 30.

To calculate your own foot size, you need to divide its length by two and add the result to the length. For example, the length of your foot is 28 cm. 28/2 = 14. Now 14 + 28 = 42. So, 42 is the shoe size for a foot length of 28.

Some more interesting facts about legs

  1. We cut our toenails 4 times less often than our fingernails. The reason is that they grow 4 times slower than fingernails.
  2. We walk quite a lot throughout our lives. If we were to calculate the distance we have walked throughout our lives, it would be equal to the length of 4 revolutions around the planet Earth.
  3. People in standing professions – teachers, salespeople, hairdressers – put more than hundreds of tons of stress on their legs every day.
  4. The most risky part of the body, which breaks and gets injured most often, is the legs.
  5. Ankle pain is a common symptom in obese women. Overweight women may experience leg pain 4 times more often than their normal weight peers.
  6. Walking is an almost foolproof remedy for diseases. Walking can cure most diseases, especially those associated with excess weight. This is probably why doctors most often recommend walking as a disease prevention measure, rather than other sports.
  7. The feet are the parts of the leg where the thickest layer of skin grows.
  8. Eight percent is exactly the figure by which the volume of the foot changes during the day.
  9. Human legs consist of 33 joints and 26 bones – small and large. And the largest bone among them is the femur. It is so long that it makes up to 28% of a person’s height.
