The human body is an amazing thing. It is capable of creating life, surviving horrible diseases and accidents, and tasting all kinds of good (and equally bad) food). But human bodies are also susceptible to great tragedies, from freak accidents to medical mysteries. Understanding your body and how it works is vital to not only surviving, but also to live longer. So often when something goes wrong with our bodies, it can be traced back to our diets.

 

 50 facts about human body you probably didnt know

 

“Good nutrition is an important part of leading a healthy lifestyle,” the Health and Human Services website says. “Combined with physical activity, your diet can help you to reach and maintain a healthy weight, reduce your risk of chronic diseases (like heart disease and cancer), and promote your overall health.” If you feel like you aren’t healthy, it’s never too late to change that. “A person who is not very active can start by making small changes, such as replacing soft drinks with water and adding a 10-minute walk to a daily routine,” Carly Schuna writes for Livestrong.org. And understanding your body and the benefits of good health are vital for thriving communities as well. “Better health is central to human happiness and well-being,” the World Health Organization’s website reports. “It also makes an important contribution to economic progress, as healthy populations live longer, are more productive, and save more.”

 

 

So how much do you know about your body? What you don’t know will surprise you, like how 50 percent of your hand’s strength lives in your little finger. Well, if you want to know about your body (and why wouldn’t you?), we have you covered. Here are 50 facts about your body that you probably aren’t aware of, but should be.

 

foot 

 

Twenty-five percent of bones in an adult are in the foot. Even more of a reason to get those sensible shoes. 

 

butt

 

The body’s largest muscle is the gluteus maximus a.k.a. your booty a.k.a. your twerking muscle.

 

food 

 

You will likely eat 100,000 pounds of food in your lifetime. Set a goal to make 25,000 pounds of that food pizza.

 

 eye

 

 The only part of your body with zero blood flow is the cornea of eye. It only requires oxygen.

 

ear

 

If you think you have big ears or a big nose, there’s a reason for that: both parts of your body never stop growing.

 

kiss

 

More than 278 different types of bacteria are exchanged when two people kiss. 95 percent of them aren’t harmful.

 

mouth

 

The skin cells that make up a human mouth are the same skin cells that make up a person’s vagina. Knowing this, do you see chapstick in a new light? 

 

dna

 

If you take your DNA and stretch it out, it would stretch for 10 billion miles.

 

pinky

 

Fifty percent of your hand’s strength lives in your little finger. So give it a ring or something, it works hard.

 

heart beat

 

Your heart will likely beat more than 3 billion times over the course of your lifetime. 4 billion if your prone to celebrity crushes.

 

stomach

 

The lining of your stomach changes every four to five days it from digesting itself. If only it could take a few extra pounds with it.

 

step

 

A single step requires the use of over 200 muscles. So it’s less the boots that were made for walking, and more all those muscles at play.

brain

Your brain has a memory capacity so big it could fill four terabytes on a hard drive.

 

skull

 

If you weigh 150 pounds, your skull weighs 21 pounds. So subtract 21 from 150 and you’ve got the weight you should have on your driver’s license.

 

food stomach

 

An adult stomach can hold two quarts of food. Don’t try and challenge this assessment, you’ll get sick to your stomach.

 

sleep

 

Roughly 33 percent of your life will be spent sleeping. Imagine how much TV you’re missing with all that sleep?

 

smell

 

Your body detects taste within 0.00015 seconds, making your Aunt Frieda’s fruit cake at Thanksgiving even more frightening.

 

newborn

 

 Newborn babies can breathe and swallow at the same time for the first 7 months of their life.

sneeze

 

Your sneeze could travel up to 100 mph or more. Perhaps consider carrying around a sneeze seatbelt, just in case.

 

breath

 

You take 23,040 breaths a day. One breath at a time. Many times. Thousands of them actually.

 

lips

 

Your lips are hundreds of times more sensitive than your fingertips.

 

eye move

 

Did you know that some people can actually hear their eyeballs moving? You’re trying to listen to your eyeballs now, aren’t you?

 

tastebuds

 

Most people have about 2,000 tastebuds in our mouths.

 

fitbit

 

The average human walks 100,000 miles in their lifetime. But how many FitBits you’ll go through tracking your steps in your lifetime is debatable.

 

lack sleep

 

You will die sooner from lack of sleep than from hunger. You can go 10 days without sleep before death occurs, it would take weeks to die from hunger.

 

skull brain

 

The human skull is made up of just 29 bones. This feels like very little compared to what goes inside those bones: your brain.

 

color

 

Forget 4K UHD TV’s, your eye can distinguish between roughly 10 million different colors.

 

skin weighs

 

Your skin weighs 8 to 11 pounds. But don’t worry, you lose 1.5 pounds every year in dead skin cells.

 

words

 

Most people say 4,800 words within a 24 hour period. Even more if you’re a teenager.

 

liver

 

Your liver is the only organ in your body that can regenerate. That said, this doesn’t mean you can drink more. It’s still possible to significantly damage your liver.

 

eating lifetime

 

If you isolated all the times you ate over your lifetime, it would work out to roughly 5 nonstop years of eating. With the increase of binge-watch TV, that number is likely to change. Thanks “Game of Thrones.”

 

right hand

 

Some studies show that right-handed people live longer—up to 9 years longer—than left-handed people.

 

baby fingerprints

 

After three months in your mother's womb, you get your fingerprints, which are unique to you.

 

tongue

 

Each human tongue is unique to that person, just like your fingerprints. Imagine how relieved police were when they figured out they didn’t need to keep making people stick their tongues out.

 

fist

 

Your heart is about the same size as your fist.

 

teeth

 

Ninety-nine percent of all the calcium in your body lives in your teeth. So definitely remember to floss.

 

blue eye pixaby

 

Studies show people with blue eyes are more sensitive to pain.

 

head wall pixaby

 

Hitting your head against a wall for an hour could result in a loss of 150 calories (and a splitting headache).

 

dead skin pixaby

 

Humans shed 1.5 pounds every year in dead particles of skin. Not exactly a miracle diet, is it?

 

baby bone pixaby

 

A newborn baby has about 300 bones in their body, but an adult has 206. This is because as a person grows, some bones fuse together to form one bone.

 

dreams pixaby

 

On average we only remember 10 percent of our dreams.

 

saliva

 

Your mouth produces enough saliva in your lifetime to fill two swimming pools. Regardless, you still shouldn’t pee in the pool.

 

lung

 

The surface area of your lungs is equivalent to that of the area of a tennis court.

 

blush stomach

 

When you blush, your stomach also turns red. That said, if you’re blushing because you have a crush on someone, we don’t recommend lifting your shirt to reveal your stomach. That could make things weird.

 

sleep 7 minutes

 

Most people only require 7 minutes to fall asleep. Even less if you just ate a big meal.

 

apple

 

Studies show that the scent of apples and bananas can trigger an impulse in you to not overeat, which explains why those apple pie scented candles are so popular.

 

right lung

 

Our right lungs have a greater capacity for air than our left lungs.

 

sedate

 

A person weighing 150 pounds burns 63 calories sedate (like while sleeping).

 

smile

 

It only requires the use of 17 muscles to smile, but 43 to frown. So go ahead and smile, it’s easier.

 

tastebuds old

 

By the time we turn 60, most of us will lose up to half of our taste buds.
