00:00The 28-year-old patient shows up at the hospital with distressing symptoms.

00:05He explained to the doctors that he felt really bad chest discomfort and had been coughing badly for quite some time.

00:11The medical staff knew right away there was no time to waste, so he was scheduled for an x-ray.

00:17Weirdly, there was nothing unusual about the x-ray results.

00:21The patient just had a mass in his lungs that they needed to remove as soon as possible.

00:26Sure, it wasn't the best news for the man, but it was certainly nothing the doctors hadn't seen before.

00:31But that first opinion changed on the day of the surgery.

00:35Not only was the whole operation more difficult than they had initially expected,

00:39but the mass they removed from the patient had an unusual shape.

00:44When the probe was sent for further investigation, the doctors were puzzled.

00:48It was a small fir tree!

00:51The doctors that had participated in the operation thought that the man must have inhaled a seed which settled inside the man's lungs.

00:59After the seed grew into a sapling, its little needles started to damage the tissue surrounding it,

01:05which resulted in chest discomfort and coughing.

01:08As the story gained more popularity, scientists weighed in on the mysterious story.

01:13And they weren't so quick to accept it, saying it was most likely made up.

01:18On one hand, most plants need a lot of sunlight to grow, which isn't available in a human lung.

01:24More so, if it were that simple, we'd all have things growing in our bodies.

01:29Small seeds aren't that hard to swallow or inhale, right?

01:33This wasn't the only story about plants growing in a human lung that baffled scientists.

01:39In 2010, a man from Massachusetts was hospitalized after his lung collapsed.

01:45This didn't seem to take doctors by surprise, as unfortunate as it was,

01:49because the patient already had a history of respiratory issues.

01:54Nevertheless, they discovered a mass inside the man's lung and removed it immediately.

01:59What they found was equally as surprising as the fir tree, a small pea plant.

02:04Only this time, doctors suggested that the man probably had peas for dinner.

02:09But that one simply went the wrong way and didn't end up in his stomach as it should have.

02:14Once it reached his lungs, the small pea got comfortable and began sprouting leaves.

02:20The truth is a bit more complex in this case, but it does make it more plausible.

02:25Turns out that the piece that was removed from the man's lung was only about half an inch long,

02:30something that small doesn't qualify as a full-grown plant.

02:34But the seed was able to grow, though.

02:37That's because a pea seed can sprout even without light.

02:40It naturally does that underground.

02:42The seed doesn't need to have any light at this point because the tiny seed has enough energy stored inside

02:48to help it grow to the level of the soil where it gets the sunlight it needs to continue.

02:54Because of their relationship with the sun, plants are called autotrophs,

02:59or organisms that use exposure to light to feed themselves.

03:03A lot of us think that plants get their daily menu from the soil we place them in, but that's not feeding them.

03:10Plants need sunlight, water, and the gases in the air to produce glucose, the substance they use for food.

03:17This whole process is called photosynthesis and is performed by all plants, algae,

03:23and even a bunch of microorganisms, like the purple sulfur bacteria.

03:28Now back to our unfortunate human patient.

03:31While it's true that the pea seed might have germinated since it had sufficient moisture in there to survive,

03:36it didn't grow into a full-sized plant.

03:39It would have needed sunlight for that so that photosynthesis could begin.

03:43That's not to say it wasn't damaging or dangerous.

03:47So, check this out.

03:48There are people who can bend down their pinky without bending the ring finger.

03:52But most find it hard or even impossible to do.

03:55When they move their middle or little finger, they tend to slightly bend their ring finger too.

04:00Yep, me too.

04:01Globe luxation is an extremely rare condition when people can make their eyes protrude out of their sockets.

04:08Unfortunately, this ability comes with downsides.

04:11It can cause numerous eye issues.

04:13Some indigenous groups of people, like Tibetans, can survive at altitudes as high as Mount Everest.

04:19This rare ability most likely appeared after years of evolution.

04:23The ancestors of modern Tibetans lived in high regions for thousands of years and developed red blood cell adaptations,

04:30making it possible to survive with dangerously low levels of oxygen.

04:34The Bajau are sea nomads living in Southeast Asia.

04:38These people have evolved an extra-large spleen, serving as a repository of oxygen-rich blood cells.

04:45Thanks to that, they can easily spend 5 to 10 minutes fishing underwater without coming up for air even once.

04:53Now, about 14% of the population don't have a palmaris longus muscle.

04:58It's actually a rudimentary part of the body, and the need for it disappeared in the process of evolution.

05:04So, if you don't have this muscle, worry not.

05:07Its absence doesn't affect the work of your forearm anyway.

05:10About 5 to 37% of people don't have wisdom teeth from birth.

05:15These teeth are not really needed anymore.

05:18They're important for our ancestors since they help to chew hard food like nuts, roots, and meat.

05:24And saltwater taffy.

05:26Nah, I made that up.

05:27But since most of the food we eat today is processed, wisdom teeth are now a mere atavism.

05:33Most people have just one clockwise hair whorl, but 5 out of 100 people have a double crown.

05:40And if both whorls are directed counterclockwise, this makes a person even more unique.

05:45Some scientists think there's a genetic link between hair whorl direction and handedness.

05:50A bit more than 8% of right-handed people have counterclockwise hair whorls.

05:55But in the left-handed, this number grows up to 45%.

06:00A man's brain gets older faster than a woman's.

06:03As men age, they start complaining about memory problems and lack of concentration more and more often.

06:09At the same time, women don't have such acute problems with memory, but they feel depressed more often.

06:15Hmm, which one would you choose?

06:18Now, when someone is lying, their own nose gives them away.

06:22Psychologists from the University of Granada have discovered that when a person tells a lie,

06:27the temperature around their nose and in the inner corners of their eyes goes up.

06:31This phenomenon got the name of, wait for it, the Pinocchio effect.

06:36As for why fingernails grow faster than toenails,

06:39the short answer may be the fact that we use our hands more than your feet.

06:43As such, our fingernails are more exposed, and we may have evolved to grow them faster.

06:49The more you use a certain part of your body, the more it becomes exposed to damage.

06:54So for me, I'm in danger of my mouth falling off.

07:01Getting back to our hands, it's about time we give a nice shout-out to our humble pinkies.

07:06We don't see them as being really that important, since we don't use them for holding objects, eating, or writing.

07:12But recent studies have shown that losing the pinky on our dominant hands would have a devastating effect.

07:19Specialists haven't gathered enough data to supply specific numbers, but from what they've learned so far,

07:25losing our pinky would weaken our grip strength considerably, even if it's the lesser-used finger.

07:31Adding the ring finger to that, and the effect would be worse for our grip strength.

07:37Another recent study done in the UK has shown that only about 40% of people are happy with how their nose looks.

07:45Regardless of how you feel about it, the human nose is a real-life superhero.

07:50That's because it acts as a heater, filter, and humidifier all at once.

07:55Inside each nostril, there are small, shelf-like bones that feature blood vessels.

08:00They heat the air up before it reaches other parts of our respiratory system.

08:05The mucus that's inside there handles making the air more humid.

08:10As for the filtering part, that's why we have nose hairs.

08:13Small particles get stuck on these small hairs, which helps prevent pollen, spores, viruses, or bacteria from reaching our lungs.

08:22Now, when watching cartoons, we're led to believe that the sound our heart makes is because it's touching its environment while beating.

08:30Well, it turns out that sound is actually made by the opening and closing of the heart valves.

08:36They're like small doors inside our hearts that open and close to pump blood correctly from one side of the heart to the other.

08:43For our bodies to work, blood needs to move at the right time and in the right direction, or else.

08:51Now, let's talk teeth.

08:53Throughout your entire life, you'll probably spend up to 40 days total just brushing your teeth.

08:59And in case you're still wondering, teeth are not in fact bones, even though they do have a lot in common.

09:05One of the primary differences between bones and teeth is that our bones can regenerate.

09:10They are living tissue.

09:12Our teeth are not, and they remain permanently damaged once broken.

09:17Now, here's another shocker.

09:19We are the only species on this planet to have a chin.

09:23There's still some debate about this subject in the scientific community.

09:26But one of the reasons why seems to be to make our jaws stronger.

09:31As humans have continued to evolve, their teeth and the muscles in their jaws got smaller and smaller.

09:37So, they needed something to help with increased jaw resistance.

09:42Now, most of us have developed some specific traits depending on the area of the globe in which we live.

09:48But there is a group of people, specifically those who live in higher altitudes, that develop some pretty cool traits.

09:55That's because high altitude environments come with less oxygen.

09:59Not only do these people survive in these locations, but they've adapted so well that they actually thrive.

10:06In the Andes Mountains of South America, people have evolved red blood cells that can carry much more oxygen.

10:13It makes their overall circulatory system much more efficient.

10:17People living in Tibet have to endure similar conditions, but surprisingly, they have adapted differently.

10:23In Tibet, they can take more breaths so that they can properly oxygenate their bodies.

10:30Hey, can you speak up? I just ate an entire pizza.

10:34That's because after eating a hearty meal, our hearing tends to be a bit less sharp.

10:39During digestion, most of our bloodstream is directed toward the stomach, which takes away a bit from all the other organs.

10:46So, next time you wanna go listen to your favorite band at a live concert, make sure to eat a lighter meal.

10:52A lighter meal to keep your ears pitch perfect.

10:55On top of our stomach and left kidney, we have a magical organ that can grow back if we remove a part of it.

11:02Our liver can regenerate itself by making new cells called peptocytes.

11:07They begin to multiply once the liver is damaged.

11:10The seriousness of that damage defines if it can regenerate completely and the amount of time it takes to do so.

11:18Ever wondered what's worse for your body?

11:21No sleep or no food.

11:23Turns out the lack of sleep is more dangerous.

11:26That's because if you don't rest, your body becomes exposed to a lot more risks.

11:32After 24 hours without any shut-eye, you can start to have memory problems and find it difficult to concentrate.

11:39At just 17 hours without sleep, you start to feel tired and groggy, irritable, tense, and more emotional.

11:47I need a nap.

11:48Your pain receptors also become more sensitive, which means everything hurts a bit more than it should.

11:54Oh, and it also affects your hearing too.

11:57What?

11:58On the other hand, you can be well into your 24-hour period with no food before your body realizes you've stopped eating.

12:06In the first 8 hours, you just keep digesting the last meals you had.

12:10After those first hours, you start to use stored fats for energy.

12:15Not eating for more than 24 hours means that your body will start eating away at its own protein,

12:21which means you literally start to lose muscle.

12:25Rainwater isn't always safe to drink.

12:28It can sometimes hold harmful bacteria and viruses.

12:31Also, in heavily polluted locations, it may even meet other harmful materials.

12:37Some communities out there do depend solely on rainwater as their primary source of hydration.

12:43But does rainwater have any other health benefits?

12:46Not really, according to current studies.

12:49Some of those risky substances may be removed from rainwater if you boil it.

12:54But it's best to stick to the safer side and only drink water from sources that are 100% safe for human consumption.

13:02Now, we produce sweat mostly to regulate our body temperature and for some added moisture,

13:08like the one we need in the palms of our hands for a better grip.

13:12But sweat doesn't just show up on our skin.

13:14It comes out of around 5 million pores on our bodies.

13:18We're literally stepping on a quarter of our bones each day.

13:22We have just over 200 bones in our body, but about a quarter of those are in a very small surprising area – our feet.

13:30Since we have 26 bones in each foot, we end up with literally 52 in both.

13:37You may have this rare body feature already and not know about it since sometimes even an x-ray can't spot it.

13:43Most of us have 12 pairs of rib bones, which means we were born with 24 ribs.

13:49There are some folks, though, that actually have 25 ribs.

13:54Only 1 in 200 people have this rare extra feature, and it's called a cervical rib.

14:00It generally appears above the first rib, right at the base of the neck and above the collarbone.

14:06It's nothing to worry about, though.

14:08Most of the time, they're unnoticeable, and if ever painful, they can be safely removed.

14:14Do you know how huskies can sometimes have their eyes in different colors?

14:18Some people come equipped with this rare feature, too.

14:21The medical term for it is heterochromia.

14:24The name comes from the ancient Greek word heteros, which translates to different, and chroma, which means color.

14:32People with this condition can either have complete, central, or partial heterochromia.

14:38The complete type means that the person has two completely different colored eyes, say, one brown and one green.

14:45Two different colors in the same eye are what specialists call central heterochromia.

14:51A person with a partial heterochromia has just a portion of their eye of a different color.

14:56You can either be born with this condition or get it, say, after an injury.

15:01Still, it's extremely rare.

15:03Less than 200,000 people are diagnosed with it in the US.

15:07Either way, let's face it, it does look pretty cool!

15:12Speaking of eye color, wanna try guessing what the rarest one is?

15:16I'll spare you the Google search.

15:18It's gray.

15:19Blue eyes may have been your first thought, and they are indeed already pretty rare.

15:24Only around 8-17% of the world's population have this eye color.

15:29When it comes to gray eyes, though, they're even more special.

15:33Less than 1% of people have them.

15:36This rare body feature is caused by a lower level of melanin in the eyes' layers.

15:41If you're interested in meeting someone with gray eyes, your best chance is in Eastern and Northern Europe.

15:48Even rarer eye colors are red or violet, but these can sometimes be the result of different health conditions.

15:55There are people out there who have the superpower of seeing 100 million different colors without the help of any fancy gadgets.

16:03We see colors thanks to some cells in our eyes named cones.

16:07Most of us have three types of cones to help translate what we see into the colors that our brain is able to understand.

16:15However, specialists think that there's a small group of people called tetrachromats who have four types of these cones.

16:22So far, researchers have only been able to identify women with this condition.

16:28That little teardrop-shaped ball hanging in the back of your neck, you know, the one that helps with swallowing your food, is called a uvula.

16:36The name comes from Latin and translates to little gray.

16:40Surprisingly enough, around 2% of people are born with a bifid uvula, which means that this indispensable organ in them is either split or forked.

16:50You sure can surprise others with this cool feature of yours at parties.

16:54Joking aside though, people with this bifid uvula may sometimes have trouble eating, drinking, and speaking.

17:01They might also have issues with digesting food.

17:04Their speech may also sound a bit unusual, but this depends on how much the uvula is split.

17:10Now, nobody really knows why we need the appendix, but it's always at the back of the book.

17:16Wait, wrong appendix.

17:18Some researchers claim the human appendix helped our ancestors process the tree bark and whatever they were eating at that time.

17:25As we have a way more balanced diet now, the appendix can disappear from our bodies without any consequences.

17:32Another purposeless thing in our bodies is the wisdom teeth.

17:36Yeah, they used to come in handy when dentists didn't exist, but now we can ideally make do without them.

17:42Your brain will grow by roughly 2% if you venture into space.

17:47Under normal gravity, it's thought that fluid in the brain naturally moves downwards when we stand upright.

17:53But there is evidence that microgravity prevents this, resulting in fluid accumulation in the brain and skull.

18:01When you age, your brain is gradually reducing in size.

18:04By age 75, it's much smaller than at age 30, and it starts shrinking at 40.

18:10It happens to everyone, so you just have to go with it and keep your brain busy and nimble.

18:16If you stare into your eyes in the mirror, you'll see a small pink circle settled in the corner of your eye.

18:22This is your third eyelid.

18:24Useless for us, but valuable for animals, like birds, to keep dust and scattered debris from getting into their eyes.

18:31This might sound familiar to you if you've heard of natural selection.

18:35In short, natural selection keeps body parts throughout generations, but some of them are harmful,

18:40so they're phased out in the next generation and others that aren't staying, just like the third eyelid.

18:46Not only your brain shrinks as you get older, you too shrink dramatically.

18:52The bones get more brittle, the backbone gets compressed.

18:55It works vice versa too.

18:57When you rest at night, your bones kinda relax too, so you wake up taller than when you went to bed last night.

19:04Our ears help us keep the balance, so hearing isn't their only duty.

19:09Our vestibular system occupies the inner ear.

19:12Canals in your inner ear contain fluid and tiny sensors that look somewhat like hairs, helping you keep your balance.

19:19As for hairs, only a few body parts aren't covered with them.

19:23These are palms, the soles of the feet, and lips.

19:26Hairs grow even in the belly button.

19:29Their purpose is to catch lint.

19:31Mine does a great job.

19:32And not only lint, our belly buttons have an entire animal encyclopedia in them,

19:38with a range of about 70 different bacteria.

19:41Some of them can also be found in soil in Japan, and even some bacteria typical for polar ice caps.

19:47See, you have a whole naval expedition going on and didn't even know it!

19:53Only about 43% of you is you.

19:56You're over 50% tiny little creatures that mainly live in your gut and other body parts without ever leaving it.

20:03Still, even though your cells are fewer than microbial ones, there are, on average, about 100 trillion of them in you.

20:11With this in mind, your genes are less than half of what you consist of.

20:15If you take all the microbes dwelling within your body and count their genes,

20:19it'll be anywhere from 2 to 20 million genes and their combinations.

20:24If you sleep, and I recommend that you do, it doesn't mean all of your body sleeps.

20:30In fact, sometimes your brain has to work even harder when you're asleep.

20:34It needs to process tons of information, and reports usually take time.

20:39One thing that indeed rests while you're sleeping is your nose.

20:43You won't smell anything nasty in your sleep.

20:46The thing is that your sense of smell deactivates at night.

20:49If there's some terrible smell in your bedroom, you won't even be bothered.

20:53That's it for today.
