10 Body Features Not Everyone Has

All people in the world are different, and every one is unique. And yet some of us have rare features that occur in only a few percents of humans. Do you know anybody whose bones are harder than concrete? We are going to tell you about the most unusual and mind-blowing characteristics only a few people have. Some are just nice physical features, but there are those Superman himself would envy! TIMESTAMPS Incredibly dense bones 1:02 "Golden" blood 2:01 Long palmar muscle 2:50 Genetic chimerism 3:40 Double lash line 5:00 A hole near the ear 5:45 Additional ribs 6:29 Ability to perceive "invisible" colors 7:21 Small need for sleep 8:37 The impossibility of cholesterol growth 9:40 SUMMARY - Studying the gene LRP5 (responsible for the mineralization of bones), scientists discovered mutations which cause diseases accompanied by bone fragility. Yet there is another type of LRP5 mutation: it gives a person super dense bones that are almost impossible to break and skin that is less prone to aging. Such bones are several times tougher than those of an average person. - On the surface of every red blood cell, people typically have about 342 antigens, 160 of which can be found in almost everybody. If a person has a lack of at least one of these antigens, their blood is rare. - A recent study has shown that 16 percent of people don't have this thin tendon. It is too weak to affect your grip, and even if it is cut, it won't make any visible changes. - Human chimerism is an additional set of DNA. Sometimes it appears in the form of "mosaic" skin or heterochromia, but most often it remains unnoticed. - Distichiasis usually doesn't bring any inconvenience. People with this unusual feature may have just several sparse hairs growing on one lid or full lines of lashes doubling the ones everybody has. - A hole near the ear is a congenital auricular fistula, formed during fetal development, occurring in about 5% of people. In fact, in the USA less than 1 percent of people have them, in Asia and some parts of Africa this figure is higher - from 5 to 10 percent. - Every adult out of 500 individuals has an extra rib. While all the other people have two dozens, these "lucky" ones can have 25 or even 26 ribs in their body. "Excessive" ribs are more often found in women. - With a dandelion, we describe its color as yellow. A tetrachromatic person will see a whole range of shades. This condition is caused by the mutations in the X chromosome. This difference allows people to see up to 99 million colors, while an ordinary person perceives not more than 1 million. - The DEC2 gene is a small mutation found in low-sleep people. Scientists from the University of California concluded that people with the DEC2 mutation could perform all the same tasks in less time. Can you imagine, having just 4 hours of sleep daily, you will get 60 days of free time a year! - There's a tiny group of lucky people who can eat almost anything without worrying about cholesterol. Their risk of developing heart disease is reduced by as much as 90%. While an average American is straining to reach a perfect result of fewer than 100 milligrams of "bad cholesterol" per deciliter of blood, people with this mutation have about 15!
