If you are among the majority of people in the world, then, with all your efforts, you will not be able to do it.
There are always exceptions to the rules, but our body is designed in such a way that sometimes some tricks are almost impossible.
- Raise an eyebrow.
The ability to raise eyebrows is an evolutionary trait.
Most cannot raise one eyebrow, but many can learn to do it.
- Lick your elbow.
99% of people cannot lick their own elbow, and 90% who hear the news immediately try to check it out.
But some people can do this task, and every day about 5 people try to get into the Guinness Book of Records with such an amazing ability.
- Wiggle your ears.
Few know how to move their ears. Scientists have figured out the reason why not everyone can do this. In the brainstem, the ear muscles (as opposed to the facial muscles) have their own accessory nerve. Compared to animals, this part is very small in humans.
- Touch nose or chin with tongue.
Approximately 10% of people can complete this task, and 5 times more people have Ehlers-Danlos syndrome, which causes joint hypermobility.
- Tongue with a straw and other tongue tricks.
Previously, it was believed that the ability to roll the tongue into a tube is genetic and is determined by the presence of a dominant gene. Folding the tongue into a tube was often a kind of test that showed the presence of dominant and recessive genes in the class. But studies on twins have shown that this ability is influenced not only by genetics, but also by the environment.
- Sneezing with eyes open
The sneezing center in the brain sends coordinated motor impulses to the nerves that control the muscles of the abs, chest, diaphragm, neck, face, eyelids and various sphincters, all of which happens automatically. Therefore, we cannot sneeze with our eyes open.
- Tickle Yourself
Most of us have places that are most sensitive to tickling, loved ones know how to take advantage of it.
But a person cannot tickle himself. The fact is that the cerebellum, which is responsible for this response, anticipates our own movements and cancels the response of other areas of the brain to self-tickling.
- Finger trick: paralyzed finger
Do this experiment: bend your middle finger as shown in the picture, place your hand on the table. Raise your thumb, index, and pinky fingers Now try to lift your ring finger. Did not work out?
The reason is that the tendons of the fingers are independent of each other, except those in the middle and ring fingers. These tendons are tied, so when the middle finger is bent, you cannot move the ring finger. There is a feeling of paralysis of the ring finger.
- Draw number 6 by moving leg clockwise
Sitting on a chair, lift your right leg and draw circles for it clockwise. At the same time, draw the number 6 with your right hand. The leg will change direction by itself.
Also try rotating your right foot counterclockwise and drawing the number 8 with your right hand.
Another trick: twist the index fingers of both hands clockwise. Slowly at first, then pick up speed. Complete the task as quickly as possible, and soon both of your fingers will move in opposite directions.
- Holding his breath and suffocate.
It is physically impossible to hold your breath and thereby commit suicide.
We have a reflex whereby stagnant gases such as carbon monoxide and nitrogen are pushed out by the lungs by deep exhalation. Even if you force yourself to overcome this reflex, you may faint due to a lack of oxygen in your brain. After you faint, your mouth will open and your lungs will start working again.
Freediver Stig Severinsen set a record for holding his breath underwater - 22 minutes.
