Compact and flexible eyeballs .. 10 strange things in the human body did not know the existence

Superheroes may be found only in comics and films, but some of these normal human abilities - as illustrated by Hannah Hong in her report in the American magazine Reader's Digest - certainly qualify to be a superpower.

Immunity from sleep deprivation
People who have a mutation in the DEC2 gene feel fine even if they don't get enough sleep. For them, six hours of sleep is sufficient, but it is likely to have repercussions in some others.

See advanced colors
A normal eye has three types of cones, which means you can recognize colors in the red, green and blue spectrum, and distinguish between about a million different colors, according to the BBC. However, there are those who have four types of cones in their eyes, which enables them to see the shades of ultraviolet rays, and allows them to estimate 100 million distinct colors.

Flexible eyeballs
Flexible eyeballs are a very rare condition, where the eyes can protrude from their cavity. In contrast, one study suggests that the condition is caused by causes such as "thyroid ophthalmopathy" and "elastic eyelid syndrome" and can lead to optic neuropathy.

Recognize the musical tone accurately
This ability allows people to recognize musical notes accurately. In fact, one in every 1,000 people has this unique ability. While some people are born with this ability, some studies suggest that dedication and training may help develop this talent.

Second row of eyelashes
This condition is characterized by the presence of a second group of lashes that grow from the inner mucous layer of the eye. According to MedScape, this disorder occurs when epithelial germ cells fail to distinguish between some glands. Additional eyelashes can irritate the eye and cause problems such as rupture, infections and corneal ulcers.

Ability to stay alive in high-rise
The author showed that some indigenous groups, such as the Tibetan people, were able to survive in highlands such as Mount Everest. The researchers believe that their rare ability comes from their ancestors who lived in the highlands for thousands of years and who have developed the ability of the red blood cells to adapt, making it possible to survive with low levels of oxygen.

Ability to stay under water for more than ten minutes
A recent study found that the people of Bajao, nomads in Southeast Asia, developed a very large spleen that acts as a repository of oxygen-rich blood cells. They are also able to spend five to ten minutes quietly fishing underwater without going out to breathe air.

Built-in compass
The writer said history has revealed explorers who can navigate and point in key directions without a compass. Researchers at the Queensland Brain Institute found that a person's superhuman ability to find his or her path is gradually being learned, and that the brain eventually becomes in tune with trends in new environments.

Echocardiography
The author explained that dolphins and bats can navigate the world by making a sound and locating an echo. Although this ability is extremely rare in humans, some people “see in the dark” by repeating the process.

The Incredible Gourmet
The average person has about 10,000 gourmet buds. In contrast, some people have a high density in taste buds. Thanks to their strong taste abilities, they often have strong reactions to bitter foods such as broccoli or grapefruit. In fact, many people with this ability turn into professional experts.
