00:00So, check this out – there are people who can bend down their pinky without bending

00:04the ring finger.

00:06But most find it hard or even impossible to do.

00:09When they move their middle or little finger, they tend to slightly bend their ring finger

00:13too.

00:14Yep, me too.

00:15Globe luxation is an extremely rare condition when people can make their eyes protrude out

00:20of their sockets.

00:21Unfortunately, this ability comes with downsides – it can cause numerous eye issues.

00:27Some indigenous groups of people, like Tibetans, can survive at altitudes as high as Mount

00:32Everest.

00:33This rare ability most likely appeared after years of evolution.

00:37The ancestors of modern Tibetans lived in high regions for thousands of years and developed

00:42red blood cell adaptations, making it possible to survive with dangerously low levels of

00:47oxygen.

00:48The Baiju are sea nomads living in Southeast Asia.

00:52These people have evolved an extra-large spleen serving as a repository of oxygen-rich

00:57blood cells.

00:58Thanks to that, they can easily spend 5 to 10 minutes fishing underwater without coming

01:03up for air even once.

01:06About 14% of the population don't have a palmaris longus muscle.

01:10It's actually a rudimentary part of the body, and the need for it disappeared in the

01:15process of evolution.

01:17So if you don't have this muscle, worry not.

01:19Its absence doesn't affect the work of your forearm anyway.

01:23About 5 to 37% of people don't have wisdom teeth from birth.

01:28These teeth are not really needed anymore.

01:30They were important for our ancestors since they helped to chew hard food like nuts, roots,

01:36and meat.

01:37And saltwater taffy.

01:38I made that up.

01:40But since most of the food we eat today is processed, wisdom teeth are now a mere atavism.

01:46Most people have just one clockwise hair whorl, but 5 out of 100 people have a double

01:52crown.

01:53And if both whorls are directed counterclockwise, this makes a person even more unique.

01:58Some scientists think there's a genetic link between hair whorl direction and handedness.

02:03A bit more than 8% of right-handed people have counterclockwise hair whorls, but in

02:08the left-handed, this number grows up to 45%.

02:13A man's brain gets older faster than a woman's.

02:16As men age, they start complaining about memory problems and lack of concentration more and

02:21more often.

02:22At the same time, women don't have such acute problems with memory, but they feel depressed

02:27more often.

02:29Which one would you choose?

02:31When someone is lying, their own nose gives them away.

02:35Psychologists from the University of Granada have discovered that when a person tells a

02:39lie, the temperature around their nose and in the inner corners of their eyes goes up.

02:45This phenomenon got the name of, wait for it, the Pinocchio effect.

02:50Japanese people have particular bacteria in their intestines.

02:54These bacteria help them to digest sushi.

02:57The Japanese have been eating raw seaweed for centuries.

03:00Microorganisms dwelling on the surface of the seaweed got into their bodies and actively

03:05developed.

03:06Nowadays, the bacteria help Japanese people digest raw food and prevent different problems

03:11connected with food.

03:13So people have as many hairs on their bodies as chimpanzees.

03:18The hair count of a person and a chimp is approximately the same.

03:21The only difference is that human body hair is mostly useless and so fine that it's

03:26almost impossible to see.

03:29Humans don't have more genes than other species.

03:32In fact, people have fewer genes than a worm.

03:34Tomatoes also have many more genes than you do.

03:37But we are such complicated creatures.

03:40Well, recently, scientists have concluded that the number of genes that a genome contains

03:44isn't closely connected with the complexity of a living being.

03:48Let's take a breather.

03:50Speaking of which, your left lung consists of two lobes, while your right lung is divided

03:55into three parts.

03:57Plus, the lung on the left is a bit smaller since it has to make room for your heart.

04:02Your lungs also contain around 1,500 miles of airways.

04:06It's more than half the distance between New York and Los Angeles.

04:09There are also more than 300 million alveoli, which are tiny balloon-shaped air sacs in

04:15your lungs.

04:17People have 5 most obvious senses – vision, smell, touch, hearing, and taste.

04:22But that's not all.

04:24How about thermoception – the sense of heat?

04:27Or nociception – the perception of pain?

04:29Or your body awareness – proprioception?

04:32To figure out what it is, close your eyes and touch your nose.

04:35Got it?

04:36That's proprioception in action.

04:38This list can be much longer.

04:40Some experts state people have from 21 to 53 senses.

04:46So your fingers get all wrinkly after you spend too much time in the water.

04:50Pruney fingers are caused by the narrowing of your blood vessels.

04:53When you stay in the water for a long time, your nervous system makes your blood vessels

04:57shrink.

04:58Your body sends the blood away from that area.

05:00And this loss of blood makes your vessels thinner.

05:03The skin starts folding over them, forming those funny wrinkles.

05:07Scientists think this process helps us have a better grip when our hands and feet are

05:11wet.

05:12There are 3 kinds of cone cells in the average person's eyes.

05:16These cones help to recognize the colors in the blue, red, and green spectrums.

05:21Thanks to them, most people can distinguish around 1 million different shades.

05:25Those with tetrachromacy have 4 cones in their eyes.

05:28This feature allows them to see up to 100 million different hues.

05:32This vision anomaly is extremely rare, and is much more common in women than in men.

05:38Interestingly, most people with tetrachromacy don't even realize they see the world brighter

05:43than others.

05:45Not all people have round pupils.

05:47Two people out of every 10,000 have unusually shaped pupils.

05:51Most commonly, they resemble keyholes.

05:54This eye disorder is called colobobo.

05:56Interestingly, some people with this condition don't have any problems with their vision.

06:02So get this.

06:03If someone managed to uncoil all the DNA in the human body, it would stretch out to around

06:0810 billion miles.

06:09Hey, do the math.

06:11That's twice the distance from Earth to Pluto.

06:14And that's not the only awesome thing our body is capable of.

06:18Trillions of nerve connections are powering your memory non-stop.

06:22According to studies, after looking at 2,500 images for a mere 3 seconds, most people can

06:28recall if they have seen these pictures with 92% accuracy.

06:34Your body glows, emitting tiny amounts of fairly visible light.

06:38This glow is the product of biochemical reactions going on inside your organism.

06:43The light waxes and wanes throughout the day.

06:45But even though it is visible, you can't detect it with the unaided eye.

06:51From 1 to 6 pounds of your body weight is made up of bacteria.

06:55And from 100 million to 1 billion bacteria can live on just one tooth in your mouth.

07:01So please brush.

07:03It's impossible to taste your food without saliva.

07:06All because the chemicals in your food must be dissolved in saliva before they get detected

07:10by your taste buds.

07:13Even though it sounds like a myth, eating too many carrots can indeed turn your skin

07:17orange.

07:19Carrots have high amounts of beta-carotene.

07:21That's a compound that can cause keratinemia.

07:24If you have too much of this compound in your bloodstream, it'll hold onto parts of your

07:28body with thicker skin.

07:29I'm talking about the soles of your feet, your knees, elbows, palms, and even certain

07:34areas around your nose.

07:37But worry not, this condition is not dangerous.

07:39You can easily reverse it by decreasing the amount of beta-carotene-filled foods you consume.

07:46The chin muscles, scientifically known as the mentalis muscles, look pretty quirky,

07:51giving us mixed feelings.

07:53Just look at these creepy tiny tentacles.

07:55And still, they make it possible for us to create all kinds of facial expressions that

07:59involve the lips, chin, and cheeks.

08:02And yes, they are the culprits behind those weird wrinkles and crevices on the skin of

08:07your chinny-chin-chin.

08:09All because these muscles don't pull on themselves, but yank on the skin.

08:14People can live without some organs, leading a normal life.

08:17The human body consists of singular organs and those that come in pairs.

08:22And speaking of the latter, you'll only need one of those to survive.

08:26Your small intestine is actually not so small.

08:29It's taller than you, measuring around 23 feet.

08:33The cornea, that transparent front cover on your eyes, doesn't have any blood supply.

08:38Instead, it receives oxygen directly from the air.

08:42Human beings develop their unique fingerprints very early in life, while they're still embryos

08:47just three months after being conceived.

08:50By the way, even if fingerprints get badly damaged, they tend to grow back to their original

08:54pattern.

08:56All people are born with a diving reflex.

08:59It can get activated and shut bodily functions if one is drowning or is submerged in the

09:03water.

09:05The human brain is by no means smooth.

09:08But if you decided to flatten all those wrinkles covering it, the brain would be the size of

09:13a pillowcase.

09:14But not as useful.

09:16Newborn babies only blink once or twice in a minute.

09:19For comparison, a grown-up person blinks at least 10 times within the same time.

09:24Our lungs are the only organs that can float on the water.

09:27All because they're made up of around 300 million balloon-like structures called alveoli.

09:32Also, even if we're perfectly healthy, our lungs are never completely germ-free or sterile.

09:39Your nose is a superhero.

09:42It's your very own heater, filter, and humidifier.

09:45This organ is lined with tiny bone-like shells called turbinates.

09:48They contain blood vessels capable of heating the air and goblet cells that can help humidify

09:53the air.

09:54Also, the air you breathe gets filtered in your nose before going further to your lungs.

10:00Every time you eat something, your esophagus, the organ your food travels through to reach

10:05the stomach, moves in a series of wave-like contractions, pushing the food forward.

10:10This is known as peristalsis.

10:13There's a bond between your digestive system and your brain, the gut-brain axis.

10:18This is why stress or brain issues can affect the way your body digests food.

10:23Now, even though hiccups are typically harmless and resolve by themselves after a couple of

10:28minutes, they aren't exactly pleasant.

10:30So, you should probably know that they might occur because of changes in temperature.

10:36The density of your brain increases throughout your whole life, all because new neural connections

10:41pop up.

10:42They appear because the structure of the brain keeps changing too.

10:46If you don't want to sneeze, press the skin on the bridge of your nose with your fingers.

10:51When you do it, your brain receives an alarm signal.

10:54Very quickly, it puts the brake on all those other processes, including the sneezing reflex.

10:59By the way, studies have found that sneezing is your nose's way to reset.

11:04A sneeze reboots the cells that line the inside of your nose.

11:08They're called cilia.

11:10The part of your brain that's responsible for vision is in the back of your head.

11:15Interestingly, the right side of your brain controls the vision on the left side, and

11:19vice versa.

11:21If you're in some loud place, for example, in a club or at a concert, close your ears

11:26to better hear your friends.

11:29Push the tragus, which is that pointy skin-covered cartilage in front of the ear canal, into

11:33your ear.

11:34Then, turn this ear toward your friend.

11:38On average, when a person snores, the sound doesn't get louder than 60 decibels.

11:42That's as loud as a regular conversation.

11:45But sometimes, the noise level can reach 80 decibels.

11:48That's as loud as a working food blender.

11:52Just like salamanders regrow their tails, humans might be able to regenerate cartilage.

11:57That's the rubber-like stuff surrounding your joints.

12:00Scientists have recently discovered that cartilage could repair itself.

12:04This process is likely to be the most effective at the ankle, not that effective in the knee,

12:09and the least effective in the hip.

12:12If a person has asnosmia, which is also called smell blindness, they don't distinguish

12:17and detect smells.

12:20Your eyes never stop moving while taking in visual information.

12:23Otherwise, you wouldn't be able to see the whole picture.

12:27These movements go unnoticed because your brain is a great video editor.

12:31It stabilizes the images and connects tons of fragments into one smooth video.

12:37The liver is the only human organ that can regenerate completely.

12:41Even if it's a mere 25% of the original liver weight, the organ can get back to its

12:46full size.

12:49Your mouth burns when you're snacking on pineapple because while you're eating this

12:53fruit, it's eating you back.

12:55Well, kind of.

12:56Smell is the only known food that contains bromelain.

12:59That's an enzyme that breaks down proteins.

13:02Luckily, your stomach acid knows how to deal with the offending enzyme.

13:07We also have bacteria that can produce electricity living in our intestines.

13:11These bacteria give off electrons, which creates tiny electrical currents.

13:16This might be the bacteria's way to generate energy.

13:20Deja vu might actually be something like a brain processing lag.

13:26There's a theory claiming that it might happen when your brain is moving information

13:31from one part to another.

13:33If there's even the tiniest delay in that process, your brain will get the same information

13:37twice.

13:38In this case, it'll process it as an event that happened before.

13:43The DEC2 gene mutation allows people to have just a few hours of sleep a night and still

13:48feel great.

13:49They don't get tired and never sleep in.

13:52On average, such people wake up at 4 or 5 a.m.

13:56No more than 5% of the world's population has this feature.

14:01Your ears might pop or even hurt when you're on an airplane.

14:05You can solve this problem by simply chewing some gum.

14:08This opens up your eustachian tube.

14:10That's a small passage that connects your throat and your middle ear.

14:14Opening this passage helps equalize the pressure in your ears and puts an end to the popping.

14:19You can also yawn to open up the eustachian tubes.

14:23Your feet are likely to become bigger with time.

14:26Just like your nose.

14:27And your ears.

14:28You see, when people grow older, ligaments and tendons in their feet weaken.

14:32This makes the arches flatter, and the feet become wider and longer.

14:37Hey, not to freak you out or anything, but every second, your body creates 25 million

14:44new cells.

14:45I'll do the math for you.

14:46That means that in about 15 seconds, you'll have produced more cells than there are people

14:51in the United States.

14:52Think about that next time you feel you haven't been productive enough.

14:57It may account for only 2% of our body mass, but our brains actually take up 20% of our

15:02blood supply and oxygen.

15:04Our brains can also produce enough energy to supply a lightbulb.

15:08That is, when we're awake.

15:10Ever thought about what the largest human organ is?

15:13It's your skin.

15:14And it's thickest on the palms of your hands and soles of your feet.

15:18I know, I know.

15:19I hate dusting too.

15:21But you are particularly responsible for that layer of fluff on your TV screen, you know.

15:27Every human being sheds about 600,000 particles of skin every hour.

15:32And most of the dust around your house is actually composed of that.

15:35So yes, we're all rather flaky.

15:39These days, it's considered more of a beauty mark.

15:41But the reason why people are born with a Cupid's bow is actually quite intriguing.

15:46As our features start to develop before we're even born, it appears that the Cupid's bow

15:51is actually the place where our face, well, zips up.

15:55The right side of the face and the left side of the face, that is.

15:58While in humans, it may not be that obvious.

16:01If you look at your dog's nose, you'll see it has a straight vertical line just under

16:05the nostrils.

16:06That's right, dogs have this zip too.

16:10Did you know you were born with more bones than you have today?

16:13At birth, we have somewhere around 300 bones.

16:17But as we age, some of them fuse together.

16:20That's why in adulthood, we end up having about 200 bones.

16:24Although your teeth are technically part of your skeletal system, they're not actually

16:28bones.

16:29They do look sort of similar and do share some characteristics, like being the hardest

16:33element in your body.

16:35Why the misconception though?

16:37It's mostly because both teeth and bones contain calcium.

16:41To be a bit more specific, about 99% of the body's calcium is in your bones and teeth.

16:47The remaining calcium is in your bloodstream.

16:49So what makes them different, you might ask?

16:51It's in how the bones and teeth heal and how you should take care of them.

16:56While bones can repair and heal themselves, your teeth aren't able to do that.

17:00That's why we have dentists.

17:02We don't only have unique fingerprints, our tongues are one-of-a-kind as well.

17:07Research has shown that those approximately 10,000 taste buds on our tongues are laid

17:12out in a unique pattern, specific for each one of us.

17:16About 80% of what you believe is taste is actually smell.

17:20The combination of taste and smell that we perceive is what we come to know as flavor.

17:25That's probably because our sense of smell is around 10,000 times stronger than our sense

17:31of taste.

17:32So, the next time you're tuning in your favorite song, try to pay some attention to

17:37your heartbeat.

17:38Do you hear that?

17:39Yep, that's right.

17:40While listening to some music, your heartbeat will sync with the rhythm of the song.

17:45And speaking of that healthy ticker of yours, just in case you're wondering, it beats

17:49on average about 75 times per minute.

17:52This means that in any given year, a human heart can pump enough blood to fill an Olympic-sized

17:58pool.

17:59What's even more fascinating is that if you were to connect all your blood vessels end-to-end,

18:03you'd be able to circle the Earth four times.

18:06But that would really hurt, so don't try that.

18:09We are the only species on this planet to have a chin.

18:13There's still some debate around this subject in the scientific community, but one of the

18:17reasons seems to be to make our jaws stronger.

18:20As humans have continued to evolve, their teeth and the muscles in their jaws got smaller

18:25and smaller.

18:26So they needed something to help with increased jaw resistance.

18:31That transparent part of your eye is called the cornea, and it helps the light go through.

18:36It's also the only part of your body that isn't connected to any blood supply.

18:40Why?

18:41Because it's especially designed to get its oxygen straight from the surrounding atmosphere.

18:46If you took out all the fat found in a healthy human body, it would be enough to make 7 bars

18:52of soap.

18:53We also produce enough saliva in our lifetimes to fill two swimming pools.

18:57Great expectorations!

19:00Ever wondered how much we actually eat during our whole lifetimes?

19:03I'll spare you the math.

19:05An average-sized person eats nearly 66,000 pounds of food throughout the whole course

19:10of their lifetime.

19:11How much is that for scale?

19:13About 6 elephants.

19:15And that ain't peanuts.

19:17Each of us carries around 4 pounds of bacteria on average at any given time in our bodies.

19:23But hey, don't go running to the doctor just yet.

19:26Most of that bacteria is actually good and have specific functions in the human body,

19:31like digestion and our immune systems.

19:34If you want to have an accurate depiction of your height, make sure you measure yourself

19:39in the morning.

19:40That's because you're about 0.4 inches taller right when you wake up.

19:45Trust me, it isn't magic.

19:46It's merely because, throughout the day, the soft cartilage between your spinal bones

19:51gets squashed down and compressed, making you seem shorter by the time you go to bed.

19:57We know that we have some sort of energy moving around our bodies, so we actually do emit

20:02a tiny amount of light.

20:04It's too weak for our own eyes to see, though, but if you think about it, you're actually

20:09glowing as we speak.

20:11That's it for today, so hey, if you pacified your curiosity, then give the video a like

20:15and share it with your friends.
