We\u00a0used to\u00a0think there were just eight different blood types. But in\u00a0reality, there are over\u00a030\u00a0known blood group systems. Here on the Echo Woven, our favorite blood group is\u00a0B\u00a0Positive. Get\u00a0it?\n\n

For every pound of\u00a0fat you gain, you generate\u00a01\u00a0mile of\u00a0new blood\u00a0vessels\u00a0to\u00a0supply oxygen and nutrients to\u00a0your body.\n
Your stomach produces a\u00a0new lining\u00a0every 6\u00a0days\u00a0to\u00a0avoid digesting itself.\n
Nerve cells transmit 1,000 nerve impulses a\u00a0second. They travel at\u00a01\u00a0to\u00a0268\u00a0mph.\n
Our\u00a0DNA\u00a0contains 100,000\u00a0viruses. Scientists have discovered one that goes back 100 million years.\n
Your body emits visible light. You\u2019re the brightest at\u00a04\u00a0PM, and your glow is\u00a0the least visible at\u00a010\u00a0AM. Unfortunately, this glowing is\u00a01,000\u00a0times less intense than what your eyes can see.\n
Sweat is\u00a0mostly\u00a0water\u00a0mixed with\u00a0proteins,\u00a0sugars,\u00a0ammonia, and a\u00a0lot of\u00a0other stuff. It\u00a0even contains tiny amounts of\u00a0trace metals, like\u00a0copper,\u00a0zinc,\u00a0nickel,\u00a0iron, and so\u00a0on. What makes sweat taste salty is\u00a0the sodium it\u00a0contains. Plus, the more salt you eat, the saltier your sweat\u00a0is. Your body\u2019s trying to\u00a0get rid of\u00a0the excess, and the fastest way is\u00a0to\u00a0sweat it\u00a0out.\n\n

If you walked 2 mph, you\u2019d have to walk for 20 hours straight to lose 1 pound. And, it would take you 518 days and 8 hours to circle the equator.\n
Earwax isn\u2019t actually wax. It contains fat, skin cells, sweat, and dirt.\n
Your brain gets three times bigger over the first year of life and reaches its full maturity when you\u2019re 25. 60% of it is fat. Your brain generates around 23 watts of electrical power, which is enough to run a small light bulb.\n
Humans can\u2019t really multitask. Your brain can\u2019t perform more than one action at the same time. It switches between them, which doesn\u2019t save time, as you might think, but increases the possibility you\u2019ll do something wrong and makes the process longer.\n $\"\"$ \n\n
\n
When you have an exam to take, or you\u2019re at work trying to focus on an important task, try chewing gum. Research showed it can help you stay concentrated for longer on tasks that require your full attention. Studies even say that\u2019s a better test aid than caffeine.\n
There\u2019s nothing special in the gum, but the act of chewing \u2014 it wakes your brain up. The effect doesn\u2019t last long, though, just for 20 minutes.\n
Embryos develop fingerprints at 3 months.\n
Your bones are four times harder than concrete. The strongest bone in your body is the femur. It can support up to 30 times the weight of a grown-up person. Even crazier is that our bones are made up of composite material, meaning they\u2019re both hard and elastic at the same time.\n

Sunburn is\u00a0the result of\u00a0radiation exposure. When your body\u2019s natural defense mechanism gets overwhelmed trying to\u00a0fight\u00a0UV rays, a\u00a0toxic reaction occurs that results in\u00a0sunburn.\n
Goosebumps are an\u00a0evolutionary reflex left over from our ancestors. The release of\u00a0adrenaline made their hair stand\u00a0up, and they looked scarier to\u00a0approaching predators.\n
Your body produces 1\u20133 pints of\u00a0saliva\u00a0every day. It\u00a0helps you digest food and fights off infections. You also have a\u00a0lot of\u00a0bacteria in\u00a0your mouth. Yeah! The average amount of\u00a0bacteria in\u00a0a\u00a0person\u2019s mouth is\u00a0almost the same as\u00a0the number of\u00a0people living on\u00a0Earth. That\u2019s hard to\u00a0digest.\n
Each human has roughly\u00a0150,000\u00a0hairs on\u00a0their head. Every strand grows around\u00a01\/2 inch\u00a0per month. If\u00a0we\u00a0added the growth from each hair, it\u00a0would measure the distance of\u00a010\u00a0miles in\u00a0just one year.\n\n
\n

\n
Your hair is also a lot stronger than you think. A single strand can hold 3 oz, which is the weight of an apple. If we combined the strength of all the hair on your head, it could support the weight of 2 elephants. Hey, let\u2019s try it!\n
The beating sounds your heart makes are the clap of valve leaflets opening and closing. Your heart doesn\u2019t replicate its cells unless you have an injury.\n
Your corneas are the only parts of your body that don\u2019t get blood. They get oxygen directly through the air.\n
When you\u2019re sitting or standing upright, it\u2019s easier for you to recall some positive memories that make you feel good. Some believe it\u2019s because sitting up with your back flat boosts blood flow, and your brain gets more oxygen which helps it function better.\n
The man who has the deepest voice in the world can produce sounds humans, including him, can\u2019t hear at all. But elephants can hear those sounds.\n

Veins look blue because light has to\u00a0go\u00a0through layers of\u00a0skin and fat to\u00a0reach them. Your skin scatters a\u00a0lot of\u00a0the red portion of\u00a0white light before it\u00a0reflects the blood. This leaves only the blue light to\u00a0bounce back to\u00a0your eyes.\n
A\u00a0person who has\u00a0anosmia\u00a0is\u00a0unable to\u00a0detect smells.\u00a0Phantosmia\u00a0is\u00a0the opposite condition when someone smells an\u00a0odor that isn\u2019t actually there.\n
The human brain has\u00a0100 billion\u00a0neurons. It\u00a0is\u00a073% water, and the same is\u00a0true about the heart. That\u2019s why if\u00a0your brain loses even\u00a02% of\u00a0liquid, you start to\u00a0feel tired. It\u00a0also makes your memory worse, shortens your attention span, and puts a\u00a0dampener on\u00a0your mood.\n
The earliest known person to\u00a0have had blue eyes lived in\u00a0the Stone Age, 7,000 years ago.\n
Your right kidney is\u00a0probably smaller and sits lower down than your left kidney to\u00a0make room for your liver.\n\n

By\u00a0the way, your brain makes sure you don\u2019t drink too little or\u00a0too much water. After you swallow some liquid, your mouth and throat start to\u00a0fire signals to\u00a0your brain, telling it\u00a0to\u00a0stop drinking. Otherwise, you\u2019d keep gulping down water for the entire 10\u00a0to\u00a060\u00a0minutes it\u00a0takes the liquid to\u00a0get to\u00a0your cells.\n
Your eyes can see something for a\u00a0mere\u00a013\u00a0milliseconds, and your brain will already process this image. The average blink lasts from 100 to\u00a0400\u00a0milliseconds.\n
Even though the tongue isn\u2019t the strongest muscle in\u00a0your body, it\u00a0never gets tired. That\u2019s because of\u00a0the way it\u2019s built. It\u2019s made up\u00a0of\u00a08\u00a0interwoven muscles. The tongue is\u00a0the only muscle with ends not connected to\u00a0bone. Other muscles join two bones at\u00a0both ends because that\u2019s how we\u00a0pull and make a\u00a0motion.\n
There are around\u00a0700 different species of\u00a0bacteria\u00a0in\u00a0your mouth. Over 6\u00a0billion of\u00a0them live there.\n\n

Your skin is\u00a0your\u00a0largest organ. It\u00a0can cover the surface area of\u00a02\u00a0bath towels. It\u00a0accounts for around\u00a016\u00a0percent\u00a0of\u00a0body weight\u00a0and is\u00a0around 22\u00a0square feet.\n
If\u00a0you typed 60\u00a0words per minute for\u00a08\u00a0hours\u00a0a\u00a0day, it\u00a0would take you 50\u00a0years to\u00a0type the human genome.\n
You get tired pretty quickly when you\u2019re out in\u00a0the heat. This happens because your body is\u00a0trying really hard to\u00a0keep itself cool, which puts a\u00a0lot of\u00a0extra work on\u00a0it. So, you get exhausted and tired even if\u00a0you don\u2019t do\u00a0anything physically demanding.\n
Your body has 78\u00a0organs, but only 5\u00a0of\u00a0them are essential for survival\u00a0\u2014 the brain, liver, kidneys, lungs, and heart.\n\n

Oh, the phone\u2019s ringing! Must be\u00a0something urgent, at\u00a011\u00a0PM! Only… all the gadgets in\u00a0the house are silent. It\u2019s your ears that are ringing! You can also hear some hissing, whistling, buzzing, and even roaring. But all this noise doesn\u2019t have an\u00a0external source. That\u2019s why it\u2019s known as\u00a0\u201cphantom sounds.\u201d They can occur in\u00a0one or\u00a0both ears, constantly or\u00a0from time to\u00a0time. They\u2019re usually most noticeable at\u00a0night when nothing distracts you.\n
Women have more taste buds on\u00a0the surface of\u00a0their tongues than men\u00a0do. That\u2019s one of\u00a0the reasons why\u00a035%\u00a0of\u00a0ladies and only\u00a015%\u00a0of\u00a0guys are\u00a0super-tasters. Those are people who feel flavors more strongly than others.\n
Left-handed people usually prefer to\u00a0chew on\u00a0the left side, and right-handed people… well, you guessed\u00a0it… chew on\u00a0the right.\n
Even if\u00a0your fingerprints are damaged, they\u2019ll grow back in\u00a0the same unique pattern.\n
When breathing, a\u00a0single lung only uses\u00a05% of the oxygen you\u2019ve inhaled.\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n","protected":false},"excerpt":{"rendered":"
