Oh, you thought I was talking about space or something?
No, it's your own body and all its wonders.
Every single second, there are 100,000 chemical reactions going on in that big brain of yours.
Breathing, blinking, moving muscles and controlling your body like a marionette.
Your brain stays busy around the clock.
For such a complex machine, the human brain is mostly water, about 70%.
That's why going without water is a more immediate problem than going without food.

I can't go to space.
Well, trust me burping happens when liquid separates from gas in the stomach and there's Only occurs thanks to gravity.
The heart pumps blood at such a pressure that it could raise it up to the fourth floor of a building, and it takes 45 seconds for your blood to pump from your heart through your whole body and back to home base.
It also pumps 2000 gallons of the stuff in a single day.
That's almost a CZ, much as a concrete mixer truck and whole information moves along nerves at about 200 miles per hour, getting from one place to another in a matter of milliseconds.
And that's why you jerk your hand back so quickly when you accidentally touch that high pizza pan.
Your brain has 86 billion nerve cells that joined to create 100 trillion connections for comparison.
Our Milky Way galaxy contains on Lee about 300 billion stars.
The body's fastest muscles are in the eye, and the blink of an eye is about 1/10 of a second.
You do that 20,000 times a day.
Adults may blink an average of 15 times a minute, but babies do it only once or twice a minute.
The reason is still unknown to scientists.
Just don't challenge any babies to a staring contest.
There are 250,000 sweat glands in your feet, and they produce about half of pine of sweat in a single day.
Do your feet smell?
Actually, your nose does the smelling.
Your feet just stink.
A dog's sense of smell could be up to 100,000 times stronger than a human's, but you can still distinguish a trillion distinct odors.
Your body's natural smell is absolutely unique, except if you have a twin after birth, many babies have blue eyes that go darker with time.
It's because the amount of melanin, the pigment that gives your eyes, hair and skin their color in the iris is gradually increases.
During the first couple years, newborn baby see the world in black and white and upside down thehe bility to distinguish colors and flip.
The picture on Lee comes later.

Your nose and ears never stop growing throughout your lifetime.

In 85% of people air moves through one or the other, and this mazel cycle changes throughout the day.
Blushing is caused by a burst of adrenaline, and when your cheeks blush, so does your stomach.
A person produces enough saliva in a lifetime to fill two swimming pools.
That's a spit load of saliva.
The tongue consists of eight interwoven muscles.
It's structures like an octopus is tentacle or an elephant's trump.
Despite common belief, the tongue is not the strongest muscle in the human body.
That would be the jaw muscle.
Ah, human bite equals £200 of force, much less than alligators and charts.
They go into the thousands of pounds of force, but it's still more than a Parana, just like your fingerprints.
Tongue prints are unique for every individual, except for humans.
There's no other creature on earth that has a chin.
Even our eight cousins, like gorillas and chimpanzees, don't have one.
It's still a mystery for scientists.
Well, where else would we put our beard?
Speaking of which, ever noticed how some men have brown hair but a red beard?
It's because they have one copy of the M C one RG.
When a person has two copies of this gene, they're fully redheaded.
When you're listening to music, your heart starts beating in sync with the rhythm of a song.
That's why they say classical music is good for you.

Thes Asia is a phenomenon where people hear a sound and see a color with it.
Many famous musicians have had it.
The cornea of the eye gets oxygen right from the air because there's no blood supply to it.
The fingernails on your dominant hand grow faster and your fingernails grow faster than your toenails.
It all has to do with how often you use a digit the more you use it, the faster it grows.
Human fingertips are so sensitive they can feel ridges in an object, even when they're just 13 Nana meters deep.
For comparison, a Nana meter is one millionth of a millimetre, and a millimeter is about the length of a grain of sand.
According to recent research, the appendix isn't pointless at all.
Scientists found that its stores good bacteria that have a positive effect on immune health.
Similar story with your tonsils and you can live without both.
An adult skeleton is composed of 206 bones, the strongest of which is the femur.
It can stand 30 times the weight of a person's body.
Yet we're all born with 300 bones, some of them fused together as you age, even into early adulthood.
If someone touches your middle toe while your eyes are closed, you probably wouldn't be able to tell which toe is being touched.
Try it and let me know how it goes.
Running and walking would be a challenge without a big toe.
It's the most important one, bearing 40% of the body's wake.
If you go into space, you can grow up to two inches taller.
You can thank zero gravity for expanding the disks in between each vertebra.
They get squished here on Earth.
While listening to this fact, 50,000 cells in your body were replaced with new ones.
Ilian is thehe mount of Adam's theat.
Average adult body is made up of that 8,000,000,000 or seven, followed by 27 zeros.
Tomatoes have 7000 more genes than humans.
Just goes to show you more.
Doesn't always mean better.
A caterpillar has more muscles than you do.
While we have about 650 they have 4000 again.
Strength isn't always in numbers.
Human sweat is actually odorless.
It's the bacteria on your skin that interacts with the sweat and produces that smell.
Every person has the same number of fat cells, no matter how thin or plump they are.
These cells just get bigger or smaller, and you can't get rid of them with diet and exercise.
Humans have the same number of hairs on their body as chimps do.
Most of ours heir to fine and light to be seen.
So a thicker natural coat would be nice and winter, especially in Dayton.
