25% of people sneeze when they're exposed to direct sunlight. It's called the photic sneeze reflex.
I have this too. It can be helpful when you have a proto-sneeze that doesn't want to come out. Look at a bright light...ah-choo!

I know it's not quite the same, but if I have a sneeze that won't come, I look into a light or towards the sun to help bring it on.
Me too! I only recently learned that doesn't work for everybody

I have this (also known as Autosomal Dominant Compelling Helio-Ophthalmic Outburst (ACHOO) syndrome and all i got was this lousy acronym
I have it, but it's not consistent. Sometimes I sneeze, sometimes not.
I always sneeze exactly twice. And the very first thing my baby son did the first time the sun hit his face was to sneeze. Twice.
I have this and now I can't go outside without sneezing and it's annoying
Doesn't need to be sunlight. When I sit in front of the computer it happens.
My ex husband has this. Every time he needed to sneeze he would go outside and look at the sun and low and behold he would sneeze.
I love it, it's liberating and that's why I sometimes provoke the sneeze by staring at the sun ...
I have this. When the sun hits my eyes, I sneeze 3 times every time.
I have quite a few things on this list, including RH negative blood group, this sneezing when bright sunlight reflects off something, Reynauds disease, taste the soap in cilantro and several more, but also have one not mentioned here - I hear pain. My own of course . It’s very annoying, for example if I have a nagging pain and need to sleep the noise of it keeps me awake? I don’t think this is a normal thing?
While annoying, it's also handy when you feel like you need to sneeze, but can't. Such a relief!
This is one of the most annoying thing in the world. You walk outside on a sunny day, feeling fine, then all of a sudden 3 or 4 sneezes guaranteed! For me if I swallow after sneezing, it brings on another one.
yeah i have this too. its the worst in spring cuz the polin doesnt help
This comes to us from our ancestors who lived in the caves. As caves are closed and surrounded, sneezing can have very harmful effects as the viruses and bacterias can spread to other people, thats why it was much safer to sneeze outside
I highly doubt your reasoning for the existence of this trait. For it to be an effective against spreading infections, the majority, not a mere 25% of the cave dwellers would need to carry the trait. As we know by the facts of covid19, it takes only a handful people to wipe out entire populations. Besides, having an uncontrollable urge to sneeze in the open sunlight would have made the cave dwelling trait carriers vulnerable to predation. So let's just accept it for what it is - just a fun human factoid.
Load More Replies... I'm in the club! This can be a helpful reflex, for instance if you have a sneeze that wants to happen but is just on the verge, I can look at a bright light and make it happen.
i don't do this but i sneeze when i feel like i need to throw up, and after i cough (even fake coughs), and when I smell seafood.
I also have this, but it's amazing how many people don't believe me since it is not their experience.
I have this. If I ever need to sneeze and it won't come out I just look at the sun. Makes me sneeze every time
I've had this my whole life, I was once told it's to do with the air and dust around you rising with the heat and irritating your nose, which would surely apply to everyone, hmmm interesting indeed.
Who ever said that obviously has never experienced it. I can feel it like a switch beside my nose when I turn my head in the sunlight, trying to get the right angle to set of the sneeze.

Husband and Father-in-law both have this. When I notice my husband looking up and down with the sun, I preemptively say, "Bless you."
We used to have sneezing competitions with my sisters. We all have this.
Both of my siblings and I have this. We used to joke that we were allergic to going outside.
I hate this so much, especially with the whole pandemic thing. Before you’d get a “bless you”, but now you’ll get looked at like you literally have the plague..
I sneeze the minute I’m exposed to sunlight, but it only happens the second I’m exposed. Then I don’t sneeze anymore.
30% of people can flare their nostrils on command. However that muscle has very little use and is usually weak, so a lot of people can't do it on command.
Only 12% of people have tetrachromacy - the ability to see a lot more colors than the majority of people. They can see about 10 times as many shades and colors as someone with normal vision.
Aight dangit, now I wanna know what colors I'm missing out on...Or am I not missing any at all....hmmmmm.
With 1.4 million followers and 38.5 million likes on TikTok, Knowledgesaurus is the internet’s beloved creator sharing everything interesting—facts, smart observations, and common myths—in lighthearted and fun videos. Bored Panda reached out to Knowledgesaurus to find out more about his personality and how his love for fun facts and dinosaurs won the hearts of the internet.
2% of people naturally have red hair. In order to have a child with this hair color, both parents need to possess the gene, and while redheads make up a tiny part of the population, one study found that 30% of ads have people with red hair in them.
My maternal grandma and grandpa were redheads, my mom and sister are redheads, my husband's dad had read hair, my son is a red head. Out of 23 niblings in both families, my son is the only redhead
Less than 1% of people can hear colors or see sounds (synesthesia).
9% of people can taste the soap taste in cilantro. Cilantro contains the chemical that is also a byproduct of soapmaking.
“I’m 25 years old and have been an entrepreneur since the age of 19. I found success with that early on and ended up dropping out of college. I made good money, but wasn’t happy.” At that point, the TikTok creator took a risk and decided to “stop all that and start something more fun that I’m interested in and that’s how Knowledgesaurus started. I started this account 1/1/2021 with the goal of growing it and making it my full-time job and within 110 days, I was able to reach 1 million followers, which I’m so thankful for!”
5% of people have amber eyes - golden or coppery with flakes of gold, green or brown. Amber eyes are very common in dogs, bird and fish.
Less than 1% of people have this small little hole right on their ear. Some evolutionary biologists claim this used to be a gill on humans.
24% of people can raise one eyebrow, however you can learn to do this as well.
When asked how he came up with the idea for the "How Rare Are You?" series, Knowledgesaurus said it started after making a bunch of videos and seeing what people enjoyed watching. “I realized that people love to know information about themselves and love statistics. So that’s how the series began.”
“I always loved knowing random useless information to surprise people with,” the content creator said and added: “I think it all started when I was younger. If someone was talking about something I didn’t know much about, I would go and look up stuff about it and find interesting information about that topic so I could have a better conversation next time.”
10% of people have something called Morton's toe. It's when your big toe is shorter than the one next to it. The Statue of Liberty actually has a Morton's toe as well.
Only 33% of people can whistle. Almost everyone has the ability to whistle, it just takes the right techniques.
Well, if you can't whistle it's because you didn't eat the crusts of your bread. Or so my mother claimed.
Only 1% of people are ambidextrous - they have no preference for the use of right or left hand.
1% of people need less sleep than the rest of us. These people have Sleeper Syndrome which allows them to go through a sleep cycle faster than an average person.
35% of people have no wisdom teeth. Wisdom teeth used to serve a purpose but now they no longer do, which is why we take them out so they don't get infected while they're pushing through your gums. If you don't have wisdom teeth, I'm jealous of you.
35%?? Everyone I know has or had wisdom teeth. Does this occur in certain populations?
83.7% of people can roll their tongue, but only 14.7% of people can make a clover out of their tongue.
4% of people have Raynaud's syndrome. This is when a part of your body, usually your fingers or toes, starts to turn white when exposed to low temperatures. It's your body's overreaction to cold or distress.
I have this! It's incredibly painful & feels like the worst kind of pins & needles imaginable.
Only 10% of people have Darwin's tubercle - the little bump on the outside of your ear. It's believed that people who have this are better at sensing voice tonality.
Less than 1% of people in the US have AB-Negative blood. There's also something called Golden blood, which only about 40 people in the world have, and it's completely different than any other blood.
16% of people can make a roaring noise in their head using their jaw. They're able to do this because they can control a small muscle in their jaw that deafens chewing, but when it is flexed it makes a roaring noise.
I can do this too, but I thought this was something everyone experiences
Less than 1% of people have unbreakable bones. This is caused by a mutation in one of the genes that causes the bones to be up to 8 times denser.
35% of people can gleek. Only 1% of people can do it on command. Gleeking is when you're spitting saliva from under your tongue and it squirts out.
Less than 1% of people are born with a white patch of hair. It is called poliosis, which is caused by the lack of pigment called melanin in the hair follicles.
Two of my maid’s children have this. Brown and white hair. I love their hair.
Only 5% of people have arched fingerprints. Most people have looped and whorled fingerprints.
Less than 1% of people have their heart on the right side of their body. Surprisingly, this doesn't normally come with any negative consequences.
Only 25% of people have dimples. You can have either two, or just one. Dimples are also hereditary, so if either of your parents has a dimple, it's more likely you'll have one as well.
20% of people have a gap between their two front teeth. What normally causes this is a discrepancy between the jaw size and the teeth. A lot of celebrities have this and don't correct it because they think it makes them unique.
Some people believe this is an indication that you will become rich. I have yet to see anyone who has.
Only 2% of people naturally have blonde hair. If you narrow it down just to white people in the United States, that percentage goes up to 5%.
I think it depends on what you classify as blonde. Is it truly white hair or just lighter (like dark blonde)?
Only 10% of people have birthmarks. They're usually oval in shape and come in a coffee type color.
I used to have a big oval birthmark, on my lower back. But it faded as I got older and eventually disappeared altogether.
70% of people bend their head to the right when kissing. Your brain is the cause for this. The left side of our face shows more emotion so we want to give our partner the more emotive side and we tilt our head to the right.
1% of people have a double row of eyelashes. While this might look like something a lot of you are jealous of, it actually can cause a lot of problems.
Less than 1% of people have pointy or elf-like ears. It's an abnormality called Stahl's ear, it's usually corrected early in life.
Why does it need correcting? Isn't it just a cosmetic difference? Shouldn't it be up to the child to keep it or change it once they're old enough to make the decision, as long as it isn't impacting their hearing?
Only 35% of people have 20/20 vision. 2/3 people cannot see perfectly.
25% of people have perfect teeth and never need braces or any orthodontics. 45% of children need braces, but 75% need orthodontic care.
Need or want? My teeth aren't perfect and if I was an actor or something, I would've 'needed' braces, but health-wise I don't. So do they mean 75% will have health problems if they don't get work done, or just that it looks ugly?
14% of people don't have this muscle - Palmaris Longus. This muscle was developed when our ancestors were big tree climbers. If you want to see if you still have it, pull back your palm on a flat surface, touch your pinky and thumb together and slightly lift them and you should see that ligament pop out.
6% of people can vibrate and rapidly shake their eyeballs back and forth.
10% of people can touch their nose with their tongues. In medicine, this is called the Gorlin sign.
20% of people are double jointed. This is thought to be genetic and due to a variation in collagen in your connective tissues.
4% of people are colorblind. Color blindness occurs in 8% of men and 0.5% of women.
Less than 1% of people can give themselves goosebumps on command. The majority of people get them when they're cold or listening to music, but some can give themselves goosebumps whenever they want to.
yup i just have to imgine biting into a popsicle. lol i liteally got goosebumps writing this.
Only 12% of people dream in black and white.
Only 1% of the population can lick their elbow. The people that can do this usually have either a long tongue or a short forearm, or both.
Hmmmm...I wonder...:: unsuccessfully trying to lick my elbow...Wife walks in and witnesses me trying::: Wife- What the ever lovin h3ll are you doing? Me as embarrassment and awkwardness set in:: Ummm... nothing hon...nothin at all...
10% of people are left handed. Left handed people tend to live shorter lives.
8.4% of people have a counterclockwise hair whorl on their head, while the majority has a clockwise one.
8% of people still have chimp-like feet, that are specifically adapted to climbing trees. This is characterized by a mid-foot arch. If you want to check if you have this, see if you can bend the ball of your foot as well as the region half-way between your heel and the ball of your foot.
I had a hard time understanding this, because that picture is not showing the mentioned bend at all. This is what it looks like: https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcRv7izzuQZ8x4BdXJ5PzLGWd-Ogt4KLZ4xgMQ&usqp=CAU
Only 4% of people have an outie belly button. Believe it or not, doctors can't choose if you'll have an innie or an outie belly button, things like the belly button itself and the fat beneath it determine what it will look like.
Less than 1% of people have an extra rib. Most people are born with 24, but some have 25 ribs. The 25th is called a cervical rib.
25% of people have a Hitchhiker's thumb - when the upper part of the thumb can bend 90 degrees backwards. It's caused by a certain gene.
About 20% of people have a pupil that is bigger than the other. This is called anisocoria, it can be a very small, or a very big difference.
Note: this post originally had 60 images. It’s been shortened to the top 50 images based on user votes.
Fascinating post. Luckily I read it early in the morning so no one saw me trying to lick my elbow, wiggle my ears, flare my nostrils, etc.
Something else that is also rare: having both red hair and blue eyes, and it’s actually the rarest combo on earth. This is because red hair and blue eyes alone are both rare, and both parents have to carry the gene for the child to have red hair and blue eyes. I actually have red hair and blue eyes. Both my sisters have red-ish hair, but their eyes are not blue and their hair isn’t nearly as red as mine.
I have grey eyes and reddish hair. I hardly see anyone else with grey eyes.

This was fun and I had quite a few of these. Going to celebrate my weirdness!
This was so cool! Today I learned that I have twelve of these, including a few that only one percent have.
I found out recently that my blue/gold center heterochromia (blue eyes with a gold ring) is exceedingly rare. My family and I always called my eye colour “Blue Hazel.”
Does anyone know anything about sharper canine teeth? Mine are much pointier than anyone in my family.
I don't know if it means anything. My dad had them too. When he was little my nephew wondered if I was a vampire. Never thought, I could have dressed up as a vampire on Halloween and not needed the fake teeth.

I have at least 16 of these, I wonder if some are likely to be associated with each other? Morton's toe, hyper flexible, extra rib, dimples, eye brows, seeing extra colours, ear wiggling, touch tongue to nose, nostril flare, preauricular sinus, whistle, gap tooth, never needed braces, gleeking, goosebumps and snoring. I only had 3 wisdom teeth, which is quite rare as well, and a form of Synaesthesia where I experience pain as smells.
So, who else scored themselves? 11 out of 50 weird things. unfortunately, mostly useless ones. lucky in some areas like colour acuity and 20/20 vision[failing with age though].
As a people of 1, I was included in 0% of the questions, some of which I would not have answered
I have an extra muscle in my elbow called anconeus epitrochlearis. It causes pressure on my ulnar nerve sending some of my fingers numb sometimes and cause me to have a weak grip and I only have it on my left elbow.
10% of the population has 6 lumbar vertebrae. I am one if them and only found out when I needed a spinal fusion.
My stupid human trick is I can move my uvula at will and make a sound :)
My genetics prof was discussing different inherited traits. He mentioned that lobed or unlobed ears was one of them. I sat perfectly still with my one lobed ear and one ear not, trying not to be noticed.
If your not one of those from any country ( my fault but whales matter!!!) I hope we can rise and leave the ocean alone alittle. Just alittle.
Don't care if I'm the bitch. How on earth could I be that???? Yes yum, no whale obviously.

Please stop hurting whales, sharks n dolphins. I can't handle not being able to stop you.
I'm done. You next generation are too much!! Why can I not say one single thing without it being blown out of proportion??? If a Asian asked me why am I being mean against whales being murdered, I will say " "And how's your sushi bitch'. Or yes you don't understand me & I don't understand you. No worries.🙂🙂🙂
I don't judge, but your making it f*****g harder that it should be!!!!

Does the chimp feet thing count for picking stuff up with your toes, or is that something most people do on a daily basis? I do it often myself when I see something on the floor but don't to bend over.
I used to be able to peel a banana with my toes. A broken foot put an end to that charming party trick..

Wow I'm even more of an odd-duck than I thought. I can do/have a lot of these. And some not on the list, like central heterochromia, around my pupil is an amber(ish) brown, and around that is green.
Went back and counted off on my fingers, 11. And might even be 12,can't see my fingers in the darkness of my room.

I can wiggle my ears on command, and so can my Dad. I've never met anyone else that could. I'm curious what % of the population can do that... I also have red hair, blue eyes, and a bunch of the other "rare" traits listed here, so let's just go ahead and call me a freak of nature lmao
Cool! Like an activity to find out if you're special! And have hidden talents
What fun! I'm blonde (but boring old green eyes), can flare my nose, taste the soap in cilantro, have arch fingerprints, raise both eyebrows individually, have shorter big toe, sunlight makes me sneeze, have Reynaud's, only need 4 hours sleep, have hitchhiker's thumb (though never used it!), have Darwin's tubercle, can wiggle both ears, have palmaris longus, and perfect pitch.
Green eyes are incredibly rare, believe it or nto. Only 2% of the entire worlds population has green eyes, and iirc, they are the rarest eye colour aside from "mutations" that may cause different eye colours like a reddish or violet eye (albinism for example) (I also use the term mutation lightly, as funnily enough, the genes that cause a person to have green eyes initially was a mutation, same as with blue eyes, and this can be tracked down to certain specific ancestors, meaning people with green or blue eyes may be very, very, very, veryx10000 distantly related to each other xP) That means that freaking amber eyes are actually more common than green eyes. o.o So not, "boring old green eyes"!
