These are the genetic benefits of a very small part of the population.
These benefits are due to a gene mutation, a natural process that changes our DNA.
Like some genetic diseases, others have more happiness and inherit genes that give them unusual abilities.
BBC Mundo gives us five examples of some of the benefits that you might have because of your genes.
1. A complete underwater vision
Most of us see that everything is blurry if we open our eyes when we are immersed in water.
This is due to a physical problem: the density of water is similar to that of the eye fluid, and the fragile light can not enter the eye well.
That is why people usually only see good when we are in contact with the air.
However, there is one exception: Moken's people living in the Andaman Sea, the Indian Ocean sector between Burma and Thailand.
This tribe is known as the "Gypsy Sea", because most of the year they spend in huts on the water or in boats and only on the ground to stock up supplies.
If you have a wet gene, you can see it crystal clear under water.
It is believed that this genetic mutation was due to the fact that Moken spends a lot of time underwater, collects food from the seabed and floats on land on the seabed.
A scientific study, published in 2003 in the journal Current Biology, showed that the genetic mutation in the urine causes their eyes to change under water.
This makes it easy to refract when you enter your eyes and allow you to see clearly and even sink more than 20 meters underwater.
2. Tolerance to cold
Another genetic advantage observed in some indigenous people is associated with the ability to transmit low temperatures.
The human body has a normal temperature range, ranging between 36.5 and 37.5 ℃. That's why most people are more prepared to deal with hot climates than cold climates.
The normal body can not withstand extreme cold. However, there are some populations that have this ability, thanks to their particular genome.
Tribes such as Inuites that inhabit the Arctic or Nenets living in northern Russia have adapted to freezing temperatures.
Their bodies react differently to cold because they are biologically different from others.
For example, they do not interfere with cold, they have less sweat glands, their skin is much warmer than normal, and their metabolism is much higher.
These skills are purely genetic: if you move in the middle of the northern course and live there for decades, you will not gain the incredible ability of people who bear these mutations.
3. Less sleep hours
One skill that you could have, without belonging to any tribe, is good to work with less hours of sleep than usual.
Several studies have shown that most people must sleep between 7 and 9 hours so they can feel resting.
Sleep can less cause problems of concentration and health, both physical and mental.
However, a twinning study in 2014 led the US Academy of Sleep Medicines to discover that there is a genetic mutation that allows some people to need less sleep hours.
People with mutated gene DEC2 have the opportunity to have more intensive REM sleep, which makes their rest more effective.
With 6 hours of sleep or less you feel completely rested and ready for the day.
However, experts explain that this mutation affects a very small proportion of people – less than 1% of those who report little sleep.
Therefore, if you sleep a little and think that you will be fine, because you may have a genetic mutation, it is more likely that this is not the case, and you need more hours of rest.
4. Bone loss
It seems that this advantage stems from a superhero comic. A sign could be called a "man or woman with strong bones".
Most of our skeletons lose their density and bone mass when we become older. It is known as osteoporosis and can cause bone fractures and deformities.
However, there are some people who have a mutation in a gene called SOST that controls the protein sclerostin that regulates and controls bone growth.
A study by scientists in R & D at Chiroscience in Bothell, Washington, has shown that those who have this mutation do not lose their bone mass when they become elderly.
Their bones continue to accumulate density and mass over time, which gives them skeletons of the younger person.
This mutation has been found in some people of African origin, since the population of Dutch origin living in South Africa is known.
Now scientists are looking for ways to repeat this mutation in order to allow other people to reverse the aging of their skeletons.
5. Adjustment to height
It is called "soroche" by the Andean community and will not be forgotten by anyone who has suffered it. This is a discomfort caused by a lack of oxygen at high altitudes.
This altitude or mountain diseases usually cause dizziness, low blood pressure, headache and respiratory disturbances.
There are many tricks that we advise them to avoid: slowly move, eat a little, do not try to pull it well, chew the chicken. Some people resort to medication. But the truth is that even the "apunados" falls.
However, this is not a problem affecting the populations living in the mountains.
Studies conducted on Quechua in the Andes and Tibetans of the Himalayas have shown that they have genetic advantages that have enabled them to adapt to their environment.
Their carcasses are larger and have a higher lung capacity, enabling them to incorporate more oxygen with each inspiration.
And while most people produce more red blood cells when their body receives little oxygen, they produce less.
These properties are preserved even when these populations move to lower places because they are part of their genes.
Perhaps this mutation officially does not mean that they are "superheroes", but more than tourists fighting for climbing down the dead of dead rhythms and passing over the place that takes place – sometimes carrying more bags – certainly believing they have super-forces.
