[Music] [Applause] eight of the rarest physical features ever people with goldenblood supervision and no fingerprints they sound like characters from the latest superhero movie right plot twist they are as real as you and me so do you want to know how unique your physical features are then keep watching but before we get into all the details don't forget to click the subscribe button and turn on this little notification bells now you won't miss a thing number eight heterochromia have you ever seen a beautiful cat with eyes of different colors that's called heterochromia and humans can have it too heterochromia is determined by a pigment called melanin and it can be either inherited or caused by certain diseases or injuries scientists firmly believe that the main reason for it is a lack of genetic diversity moreover there are actually three different types of heterochromia complete where one iris is a different color from the other sectoral where only a certain part of the iris is of another color and central heterochromia which has a radiation of different colors from the pupil statistically speaking only six out of every 1000 people have had a row chromia but we can probably all agree that it only adds more charm to these rare individuals appearance making them look even more mysterious and unique number seven photic sneeze reflex while most of us sneeze because of a respiratory irritant or allergen of some kind people with the photic sneeze reflex do it in response to bright lights this condition affects around 18 percent to 35 percent of people in the US alone and one in every four people in general the reason for such a response to bright lights lies deep inside a person's genetics back in 2010 scientists conducted an online study of 10,000 people all the participants had to do was say whether or not they're light sneezers and let the specialists analyze their DNA the results of the study were published in the PLoS genetics journal and revealed that photic sneeze errs have only one thing different from common sneezers and it's the letter C instead of T in their DNA but even though scientists know the main reason for this type of sneeze reflex there are still no theories as to why this condition appeared and evolved in the first place number six unbreakable bones back in 1994 a man was involved in a dramatic car crash and ended up with no fractures or broken bones scientists later found out that he had an interesting genetic mutation which they called lr p5 it's strongly connected to the gene that regulates the production and release of protein which in turn plays a crucial role in bone density after digging into it more and more specialists started to find even more people with bones eight times denser than the average person in one case a person had to go through several failed hip replacements simply because his bones were so dense that doctors couldn't screw the prosthesis into them so it's pretty much useless to mess with these unique people they're so tough that it's literally impossible for them to break a bone under normal circumstances number 5 neck ribs what neck ribs is that even possible yep that's exactly what one in about 500 people in the whole world has medically speaking it's a cervical rib that arises from the seventh cervical vertebra more simply your neck a person can have a neck rib on the right left or both sides and they can vary in size and shape but don't worry these ribs rarely cause any major discomfort the only possible problem is the rib pressing on nerves or blood vessels which can lead to a feeling of numbness from time to time other than that the life of a person with neck ribs is pretty much the same as yours number four double - line do you remember Elizabeth Taylor's gorgeous long and thick eyelashes they were all thanks to a condition called distich iosys which means you have not one lash line but two from a scientific perspective it happens because of a transcription error in a person's sixteenth chromosome and is basically a genetic mutation simply speaking if your parents have it there's a high chance that you'll have it too even though it sounds like a beauty dream having a double dash line isn't as amazing as it may seem in some cases distich iasis can pose a serious threat to corneal integrity luckily there aren't that many cases of double lash line problems usually it just captures everyone's attention and makes one's eyelashes look perfect number three a Dermot olivia this genetic disorder with a long name is exceptionally rare reportedly only for extended families in the whole world have it it all started in 2007 when a woman from Switzerland contacted dermatologist Peter iton to say that she had trouble entering the u.s. because she had no fingerprints further examination of eight other members of the woman's family showed that all of them were born pretty much printless with the help of his colleagues Ayten later found three other families with a similar condition unfortunately there's still not enough confirmed information about this disorder what's known is that it all has to do with a mutation of a region of DNA called smart cat 1 that codes for protein so people with a Dermot of Livia basically have a shortened form of a skin specific protein the good news is that this condition doesn't affect their well-being at all it just makes them a little bit different number 2 golden blood we all know that there are eight blood types out there but the big news is that it's not exactly true in reality there are millions of varieties of blood types even get ready for it goldenblood this blood type is called RH no and it's the rarest one on the planet it has been reported that only 43 people in the whole world have it now that's what you call uniqueness right there the are H and O blood type often called golden blood basically lacks all 61 antigens in RH which is the largest blood system back in 1961 it was considered to be extremely dangerous since doctors were absolutely sure that a baby with no RH antigens wouldn't survive birth but as you can see they were wrong and people with the golden blood type can live happily ever after just like the rest of us however even though it sounds incredibly poetic having this type of blood isn't as cool as you may think in a serious emergency there are only nine donors out there for people with this rare blood type and we're sorry to disappoint you but golden blood is still red in color so what do you think would you like to have this blood type tell us in the comments number 1 seeing invisible colors it sounds like a superpower but it's completely true some people can totally see hundreds of colors that we can't even imagine this condition is called tetrachromacy or tetrachromatic vision and only 25 percent of people have it the thing is most of us have only three types of cone cells in our retina but not tetrachromats these guys have an additional cone cell that offers hundreds of variants for every single color you can name sounds unreal right but how can you find out if you have this fascinating feature easy neuro marketing expert professor Dianna Derval developed a very simple tetrachromacy test all you have to do is look at the spectrum and count the colors you see the more there are the higher your chances of having cool vision so don't forget to take this tetrachromacy test and tell us your results in the comments so there you go that's all for the rarest features out there which one of them would you like to have and which one in your opinion is a total nightmare tell us in the comment section below if you found this video interesting hit the like button and share it with your friends and family to find out how unique and they are if you want to see more of the fun and educational videos coming daily from the bright side of life click Subscribe and join us see you soon you
