Did you know that a human adult is made up of 7 octillion atoms? Which is 7,00,00,00,00,00,00,00,00,00,00,00,00,000 atoms! There are so many things we don’t know about our body – both weird & fascinating. Most of those are facts that pertain to features we all have.
However, there are features, just as fascinating, and super rare that only handful of us truly possess them. Have a look at these 10 rare body features and see if you have any:
1. Two differently coloured eyes
The condition is called Chimerism. It basically means that you have an extra set of DNA which can lead to Mosaic skin or heterochromia – a colour differentiation of eyes. The condition is completely harmless.
2. The rarest blood in the world called the Rhnull or Golden Blood
The blood type is so rare because it has no antigens. Anyone can receive the blood and its healing properties are better than others. There are only 40 people in the world who possess this blood type, out of which only 9 are active donors.
3. Long palm muscles that are passed down from our ancestors
It is also called palmaris longus. Basically it was a muscle that helped our ancestors climb trees. Though we don’t use it anymore, some people do have it. It can be used if someone needs a tendon graft, but functionally it is utterly useless. To check if you have it, put your arm on a flat surface then touch your thumb with your pinky finger, it will pop out of your wrist.
4. The DEC2 gene that allows people to sleep less and work more
People like Nicolas Tesla, Margret Thatcher and Winston Churchill had this problem or you may call it a blessing. The DEC2 gene basically allows a person to go through a sleep cycle in lesser time than most of us. No wonder some people used the extra time to achieve greatness.
5. The LRP5 gene mutation that gives you extremely dense bones
It sort of makes you superhuman. Your bones are extremely difficult to break and your skin is less prone to aging. However, that also means a person with this condition will have issues with joint replacement at an older age.
6. An extra hole near your ear
It’s proof that once all living things had gills. Only 5% of the people in the world have this. Again, there’s no use and neither is it dangerous. It’s just a hole near your ear. Maybe you can use it for an extra piercing (don’t!) ? It is called preauricular sinus.
7. An additional rib near your neck
This is more prevalent in women. An extra rib can sometimes be spotted near the cervical spinal region. It can vary in sizes and only causes discomfort if it grows in size. Else it’s like having an extra bone you don’t know about.
8. The deficiency that keeps away heart diseases
We all have the PCSK9 (Proprotein convertase subtilisin/kexin type 9) gene in us. However, a very small amount of the populous has it in a lesser amount. This deficiency reduces the risk of heart disease by 90%. It also means that they don’t really have to bother about cholesterol.
9. Being able to see more colours due to Tetrachromacy
Humans are mostly trichromats. But there are some of us who possess a fourth cone cell to identify colour. Basically it allows tetrachromats to see more types of colours. The world appears more vivid to them.
10. Possessing two layers of eyelashes
The condition is called Distichiasis and is not harmful in anyway. It only means that you have a second row of eyelashes. If maintained properly, it can really bring out your eyes. Elizabeth Taylor certainly rocked those.
So, how many do you have?
