1. In the morning, we are taller than in the evening

The human body is approximately 1.2 cm higher in the morning than in the evening, which is associated with the accumulation of excess liquid between the spinal discs. During the day, the body is subjected to pressure, so the liquid between the discs is evaporated.

2. A unique tongue

Everyone knows that human fingerprints are unique, and they are used as a way of identification. However, human tongue also has a unique pattern. Studies have shown that the geometric shape and the tongue texture are never repeated, so it can also be used for identification, as well as fingerprints.

3. A wonderful stomach

Our stomach acquires a new membrane once in every three days. It consists of a layer of mucus that protects the stomach wall from the gastric juice. Alcali mucus neutralizes the acid, which forms a barrier. The cells of the stomach are renewed every three days because otherwise they would not be able to withstand the effects of acid.

4. A wonderful heart

It is noteworthy that the human heart is also renewed 3-4 times in a lifetime. Previously, it was assumed that the heart can not be renewed and has the same age as the person in general. However, experts from the Medical College of New York have found that the heart contains stem cells that help it get fully renewed once in 20 years.

5. The appendix contains “good” bacteria

Recently, the researchers have found that the appendix is very useful for “good” bacteria that help the digestive system. It is something of a warehouse for bacteria, and when they disappear from the digestive system, appendix allows them to grow again.

6. Mites on eyelashes

Mites sometimes live on our eyelashes – these tiny creatures inhabit the old skin and sebum produced by hair follicles. They are absolutely harmless to health. Approximately a half of the world’s population have mites on their eyelashes.
