This post is going to be a little different than my typical posts, but hopefully just as good. Talking to a friend yesterday we started discussing how amazing the human body and mind is biologically. The mind is what really makes us individuals, but the body is a magnificent living thing that we walk around with everyday and take for granted. I just wanted to share some awesome facts with you guys and maybe it will just put a little spin on what (not who) you see in the mirror and what is working it’s so hard every single second to survive, whether we’re working with it or against it.
1.) Our heart beats around 100,000 times every day.
2.) Our blood is on a 60,000 mile journey through our blood vessels. To put that in perspective, the distance around the earth is about 25,000 miles, making the distance your blood vessels could travel if laid end to end more than two times around the earth.
3.) Our eyes can distinguish up to one million color surfaces and take in more information than the largest telescope known to man.
4.) Our lungs inhale over two million liters of air every day, without even thinking. They are large enough to cover a tennis court.
5.) Our nose is our personal air-conditioning system: it warms cold air, cools hot air and filters impurities.
6.) Your body contains enough iron to make a spike strong enough to hold your weight.
7.) The amount of time we spend with our eyes closed from blinking in one lifetime averages to 1.2 years.
8.) Capillaries are so small that it takes ten of them to equal the thickness of a human hair.
9.) The heart pumps about 1 million barrels of blood during an average lifetime–that’s enough to fill more than 3 super tankers.
10.) The human body can function without a brain.
11.) When you sneeze, all your bodily functions stop – even your heart.
12.) In 24 hours, the blood in the body travels a total of 12,000 miles – that’s four times the width of North America.
13.) By the time they’re two years old, the average baby will have crawled 93 miles (a baby!!!).
14.) When we go to sleep and enter REM (Rapid Eye Movement), our bodies become completely paralyzed as areas of the brain that control movement are de-activated.
15.) The brain is more active and thinks more at night than during the day.
16.) You can’t feel your own tickle. The brain is smart enough to neutralize the sensation. The cerebellum sends a signal to rest of the brain of your intentions and as a result the sensation is ignored.
17.) Humans share 60% of DNA with a banana (no wonder why I’ve always felt so close to that fruit).
18.) The largest cell in the human body is the female egg, male sperm is the smallest cell.
19.) The acid in your stomach is strong enough to dissolve razor blades and many other metals.
20.) The human brain cell can hold 5 times as much information as the Encyclopedia Britannica.
21.) It takes the food seven seconds to get from your mouth to your stomach.
22.) The average human dream lasts 23 seconds. Not long enough to register in the brain which is why we typically forget our dreams.
23.) Your body gives off enough heat in 30 minutes to bring half a gallon of water to a boil.
24.) The enamel in your teeth is the hardest substance in your body.
25.) Your teeth start developing (in your gums) 6 months before you are born.
26.) When you are looking at someone you love, your pupils dilate, they do the same when you are looking at someone you hate.
27.) Technically, your brain has the capacity to store everything you experience, see, read or hear. However, the real issue is recall — whether you can access that information.
28.) Information in your brain travels at different speeds: The neurons in your brain are built differently, and information travels along them at different speeds. This is why sometimes you can recall information instantly, and sometimes it takes a little longer.
29.) Your hearing decreases when you overeat. So consider eating healthy — and only until you are full.
30.) Babies are stronger than oxen: On a pound for pound basis, that is.
31.) Memory is affected by body position: Where you are and how you are placed in your environment triggers memory.
32.) Your body uses 300 muscles to balance itself when you are standing still.
33.) If saliva cannot dissolve something, you cannot taste it.
34.) An adult human body requires around 90 pounds of oxygen per day.
35.) The largest internal organ is the small intestine. Despite being called the smaller of the two intestines, your small intestine is actually four times as long as the average adult is tall. If it weren’t looped back and forth upon itself it wouldn’t fit inside the abdominal cavity.
36.) You get a new stomach lining every three to four days. The mucus-like cells lining the walls of the stomach would soon dissolve due to the strong digestive acids in your stomach if they weren’t constantly replaced.
37.) The aorta is nearly the diameter of a garden hose.
38.) Your left lung is smaller than your right lung to make room for your heart. While the lungs are fairly similar in size, the human heart, though located fairly centrally, is tilted slightly to the left making it take up more room on that side of the body and crowding out that poor left lung.
39.) The human body may appear fragile but it’s possible to survive even with the removal of the stomach, the spleen, 75 percent of the liver, 80 percent of the intestines, one kidney, one lung, and virtually every organ from the pelvic and groin area.
40.) Every year about 98% of the atoms in your body are replicated.
41.) Most laughing occurs by the person who is speaking, not the person who is listening. The person who is speaking laughs twice as much.
42.) One eye consists of more than two million working parts.
43.) In perfect conditions, our eyes can recognize candle light from up to 14 miles away.
44.) Even small noises cause the pupils of the eyes to dilate. The sound causes their pupils to change focus and blur vision. This is why surgeons require a quiet atmosphere when operating.
45.) Forced smiles can/will improve your mood because the thought of smiling and using those muscles trigger “happy” chemicals in the brain.
46.) What we perceive with our peripheral vision makes more of an impact on how our brain reacts to a scene than what we are focusing on with our central vision.
47.) Your brain reacts the to seeing someone taken an action as if we were doing that action ourselves (ex. if we see someone stub a toe, our brain reacts as if we stubbed our own toe).
48.) We are more likely to be brand loyal and/or purchase more when we are in a bad/sad mood rather than a good mood. When we’re sad, we seek the familiar, whereas, when we’re happy, we’re more likely to take risks and try something different. Related to the fear of loss.
49.) There is a theory that we can only sustain stable (not necessarily close) relationships with only 148 people at a time.
50.) People are instinctively lazy, a form of survival. Hard work(ers) are learned traits, not something you inherited like physical traits.
If that doesn’t make you appreciate this shell that we’re *stuck with, I don’t know what will. Look how awesome you are just sitting there!!!! SO FLIPPING COOOOOOOL!!!!
