00:00So, let me tell you a tale about tails.

00:04There are some cases of humans being born with a tail.

00:07There are about 25 confirmed cases known to scientists.

00:11Those born with tails, though, won't have any real benefit

00:14other than what the tailbone does for balance anyway.

00:17The tails have no function other than physically being there,

00:20as they have no bones.

00:22The tails only consist of nerves, vessels, and muscles.

00:26Now, do you find that you're a picky eater?

00:28Do you think that coriander tastes like soap?

00:31Or you can't stand pineapple on pizza?

00:33Really?

00:35Well, this may be due to what kind of taster you are.

00:38Up to 30% of people are considered super tasters

00:41and will experience different levels of enjoyment

00:43or disappointment from their foods.

00:47Food that is bitter to the super taster

00:48will likely be sweet to average tasters,

00:51who make up 40% of people.

00:54There are also 30% of people who are non-tasters

00:57and won't find anything too exciting.

01:00I guess you just have to develop a taste for that.

01:03The vast majority of people have brown eyes.

01:06About 79% of the world population share this eye color.

01:10Once, all humans only had the brown pigmentation,

01:14until around 6,000 to 10,000 years ago,

01:16and I wasn't around then,

01:18when humans migrated to Northern Europe.

01:20A mutation occurred,

01:22helping the eyes to adapt to the change of line.

01:25Blue eyes became the most common of the mutated coloration,

01:29and all of them today can be traced back

01:31to one ancestor from Europe.

01:33His name was Chadwick Abernathy.

01:35His friends called him Chad,

01:36and he was a boulder mover at Stonehenge.

01:39Well, not real.

01:40Today, blue eyes make up around 10% of the human population.

01:44Amber and hazel eyes each take up 5% respectively.

01:49Gray eyes are up to 3%.

01:51And the rarest of eye colors are green ones,

01:54consisting of only 2%.

01:56Rarer still is heterochromia iridum,

01:59where both eyes are of different colors.

02:01It's inherited and also affected by other genetic factors.

02:05Only 1% of the human population

02:07have this incredibly rare attribute.

02:09Do you have a small hole in the front of your ear

02:13above the ear canal?

02:14This is a preauricular pit.

02:17During the first 6 weeks of a child's development,

02:20long before being born,

02:21the auricle,

02:22which is the external part of your ear,

02:24will develop.

02:25The preauricle pit forms

02:27when the auricle doesn't fully fuse.

02:30This occurs in less than 1% of humans.

02:33Although there's speculation

02:34that having this little hole

02:36is the remnant of gills

02:37that we once had from our seafaring ancestors,

02:40there is nothing solid to confirm this theory.

02:43If you can lick your elbow easily

02:45or touch your thumb to your forearm,

02:48congratulations!

02:49You're among the minority of people.

02:51But some people bring flexibility to the next level.

02:54This condition is called hypermobility.

02:57It allows rare individuals

02:58to twist their bodies into weird positions,

03:01just like a snake,

03:02putting their head between their feet,

03:04doing a back bridge,

03:05and all sorts of splits.

03:07But in some cases,

03:09hypermobility can increase sensitivity

03:11because such people have a larger medulla.

03:14This brain area is responsible

03:16for processing emotions.

03:1890% of people are right-handed

03:20and only 10% are left-handed.

03:22Yes, that adds up.

03:24But there's also a very small percentage of those

03:26who can use both hands equally well,

03:29including writing, drawing,

03:31and doing any tasks.

03:33Naturally, ambidextrous people

03:34will account for only 1% of the entire population,

03:37which is about 70 million people.

03:40If you want to check whether you're one of them,

03:42try to write the same phrase with both hands,

03:44or draw a circle first with your right

03:46and then with your left hand.

03:48If there's no difference, congrats!

03:51By the way,

03:52these exercises are very good

03:53for balancing the hemispheres of the brain,

03:55regardless of which hand is your dominant one.

03:58And if you have three hands,

04:01well, that's a different video.

04:03Your fingernails grow faster on your dominant hand.

04:06In other words,

04:07if you write with your right hand,

04:08it's all right.

04:10And you'll have to trim those nails more often.

04:12Your fingernails also grow faster

04:14in the summer and during the day.

04:17Your skeleton will renew itself completely

04:19within 10 years.

04:21And yes, without surgery.

04:22An adult uses around 200 muscles

04:26just to make one step.

04:28So don't tell me I don't work out enough.

04:31Every minute,

04:32your body sheds more than 3,000 skin cells.

04:35It's almost 200,000 skin cells per hour

04:38and more than 9 pounds per year.

04:41Hey, it's the shedding skin cells weight loss plan.

04:44Ooh, sign up.

04:46But hey, don't worry.

04:47You still have about 300 million skin cells

04:49at any given moment.

04:51Plus, your skin completely renews itself

04:53every 28 to 30 days.

04:56The liver is the only human organ

04:58that can regenerate completely.

05:00As little as 25% of the original liver weight

05:03can get back to its full size.

05:06Some people can hear their eyeballs

05:08moving inside the eye sockets.

05:10Wow, that must be no fun.

05:13Unlike other parts of your body,

05:14your ears and nose never stop growing.

05:18Wow, that must be no fun.

05:21Your skin wrinkles if you stay in the water for too long.

05:23But not because it absorbs water.

05:26When your body's wet,

05:27wrinkled fingers and toes

05:29provide you with a better grip.

05:31You know, like when the treads on your car tires

05:34grip the road better when they're new.

05:36Your eyes are an amazing instrument.

05:39They can distinguish between 10 million different colors.

05:42Your brain uses more than 20% of your body's energy

05:46even when you're resting.

05:48When you're asleep,

05:49it still consumes almost as much power

05:51as when you're awake.

05:53It also burns around 330 calories per day at that.

05:57An adult person has about 25% of all their bones

06:01in the feet.

06:02Most of them are tiny but crucial.

06:04If these bones are out of alignment,

06:06so is the rest of the body.

06:08You breathe around 20,000 times a day.

06:11I've counted.

06:13Try not to stop.

06:14I actually set a personal best record today

06:16for consecutive days breathing.

06:18And I plan to top that tomorrow.

06:21Human bones are a real paradox.

06:24They're almost 5 times stronger than a steel bar

06:27with the same width

06:28but can fracture on impact

06:29and are rather brittle.

06:31If a person has asnosmia,

06:34also called smell blindness,

06:36they can't distinguish and detect smells.

06:38But they can still be smelly.

06:41Sorry.

06:42You start feeling thirsty

06:43when water loss is 1% of your body weight.

06:47More than 5% and you may faint.

06:50Water loss that's bigger than 10% of the body weight

06:53and dehydration can end a person.

06:56If you know what I mean.

06:58The strongest muscle in your body,

07:01based on its weight,

07:02is your jaw muscle.

07:03Yes, mine is way overdeveloped.

07:06At any moment,

07:0850,000 cells in your body

07:09are getting replaced by new ones.

07:12Boy, that sounds like a company

07:13I used to work for.

07:15By the end of their life,

07:17the average person can recall

07:18up to 150 trillion pieces of information.

07:22Except for where they left their car keys.

07:24Even if fingerprints are badly damaged,

07:27they still go back with their original pattern.

07:30Don't believe me?

07:31Hey, give it a whirl.

07:33Your brain's memory capacity

07:35is equivalent to about 4 terabytes on a hard drive,

07:39which is more than 8 million photos.

07:41People are the only living creatures

07:43that can naturally sleep on their backs.

07:46Even apes usually sleep in a sitting position,

07:49leaning on something.

07:50Don't wake them up.

07:51Your longest bone is your thigh bone,

07:55not your funny bone.

07:56And the tiniest one is in the ear.

07:58It's shorter than a grain of rice.

08:01Do you feel ticklish when you tickle yourself?

08:04Normally, you wouldn't,

08:05unless someone else tickles you.

08:08It happens because the cerebellum area of the brain,

08:11which monitors movements,

08:12predicts the sensations caused by your own movements.

08:15Then it sends a signal to other parts of the nervous system

08:18to cancel these sensations.

08:21But some rare individuals

08:22can actually feel ticklish on their own.

08:25If you're not among them,

08:27touching a new texture

08:28that the brain doesn't yet recognize,

08:30or using a scalp massager,

08:32can help to excite your nerves

08:33and bring relaxation.

08:36Hey, you can give it a tickle test.

08:38If you want to check out

08:40the work of your vestibular system,

08:42try this simple trick.

08:44Stand on one foot and close your eyes.

08:47Most people lose balance

08:48at least during the first attempt.

08:50Your vestibular system includes

08:52many organs and systems throughout the body.

08:55Together, they allow your body

08:57to stay in balance in different positions.

09:00This system includes the inner ear and vision,

09:03which is why keeping balance

09:04is much easier in silence

09:05while your eyes are open.

09:08Can you wiggle your ears intentionally?

09:10Are you popular at parties for doing that?

09:13Congratulations!

09:15Around 22% of people on the Earth

09:17are capable of wiggling one ear.

09:20As for moving both ears at once,

09:22only 18% can do that.

09:24Ear wiggling used to be a common thing

09:26for our distant ancestors.

09:28Scientists believe they could perform

09:30a variety of movements with their ears.

09:32The group of muscles responsible for wiggling

09:35are called the auriculars.

09:37Mostly don't need it today.

09:38But some people claim that

09:41everyone can learn to move their ears.

09:43It only takes time and practice.

09:45Unfortunately, we still cannot acquire

09:47this classy habit of twitching an ear

09:50toward a sound source,

09:51as dogs and cats do.

09:53Nor can we actually lend an ear to someone.

09:56They're challenging to remove and reattach.

09:58Next we're going on for theqiang with a man!

10:01roads in hell

10:01and something even if we try to take

10:02a hand field of назareth,

10:03where we can talk about something.

10:04I'm sure it doesn't look on of choice.

10:05Because if we don't have a pipe,

10:06or our prawdows

10:09Ela's mother of theünü,

10:10and she puts ourselves even minus…

10:11it's a place for a heart.

10:13It's one day to say

10:13that we can't guess
