The human body is composed of many different systems working cooperatively. Unlike other body systems, there are some that are essential for circulation, locomotion and posture; the muscular system being one of those. Muscles, the main constituents of this system, are organs that serve in converting chemical signals into mechanical forces which permit the movement of the body 
Our body is a wonderful creation of Universe. Nature has assigned different tasks to different body parts. We chew with our teeth, see with our eyes, hear with our ears, feel with our skin, walk with our legs and so on.
All the body parts and organs work in coordination with each other. If we neglect any body part, then the whole body suffers.

Here we will find, some Mind-Blowing facts about our body that we rarely knew...
These Facts will not only amaze you, but will change your perspective towards your body.


FACT # 01 - A Blink is a Micro-Nap

You probably thought that a blink was just something you did to keep your eyes moist or keep dust out of them. That is a very valuable service, of course, but we actually blink way more than needed for that alone—about 15 to 20 times per minute. In fact, closing our eyes briefly has been found, according to a study by Washington University, to help sharpen attention and serves as a miniature recharge.

FACT # 02 - Hair Can "Taste"

Nasal passages and lungs are lined with fine hairs, or cilia, that detect and sweep out impurities. How do they detect it? By sensing bitter tastes of the things passing through them (such as, say, nicotine). When these hairs taste something bitter, they increase their rate of movement, attempting to sweep out the bad stuff, according to a study published in the American Association for the Advancement of Science.

FACT # 03 - It's Impossible to Tickle Yourself

Your cerebellum—the area in the back of your brain that monitors movement—predicts the sensation you will feel when you attempt to tickle yourself, countering the response that the tickle would otherwise elicit in other parts of your brain.

FACT # 04 - Your Hair Helps the Environment

Dirty hair can be good for the atmosphere: according to environmental engineers at the Missouri University of Science and Technology, hair absorbs the air pollutant ozone. Scalp oils were found to be a major contributor to this, so if you want to do your part to help your local air quality, skip the shampoo! More than anything, this fact truly proves to be one of the more interesting things you didn't know about your body.

FACT # 05 -Humans "Glow," You Just Can't See It

When we talk about someone having a "glow" about them, that's often literally true. Research has found that the human body does in fact emit visible light, but since it's about 1,000 times less intense than the levels our eyes are able to spot, it's not "visible" in practice.

FACT # 06 -Stomach Acid Dissolves Razor Blades

You probably shouldn't be swallowing these things, but you might be surprised to learn that your stomach could do some serious damage on razor blades if you did. Researchers out of Meridia Huron Hospital tested the effects of gastric juice on metal objects and found that over 24 hours, the stomach acid reduced razor blades to 63 percent of their original weight

FACT # 07 -Sneezes Can Travel Up to 20 Feet

You may think you're safe when the guy all the way across the subway car sneezes, but you may be in the line of fire without even realizing it. A video study conducted by researchers at MIT found that sneezes travel much farther than previously believed—as far as 20 feet.

FACT # 08 -Hair Knows When You Sleep

One crazy thing that hairs can do: track your sleeping patterns. Researchers out of Yamaguchi University have found that our cell-rich hair follicles contain RNA from "clock genes" that express each person's sleep-wake cycle. If you get up late or go to bed early, your hair will show it.

FACT # 09 -You're Taller In the Morning Than You Are at Night

It might seem like a tall tale, but, as the folks at Business Insider explain, when you wake up in the morning, you're actually a tiny bit taller than you are when you went to bed. This is due to the pressure put on joints throughout the day. As you go about your activities, it puts causes the cartilage in your spine to compress—just fractions of an inch but enough to push everything down. As you relax in your sleep, it eases the pressure on your spinal disks and allowing you to return to your full height.

FACT # 10 -Dreaming in black and white

12% of people dream in black and white. What’s weirder is that human beings used to sleep and dream in black and white even more before color tv (~15%). The average person still dreams in color, but it’s interesting to see how the human brain is susceptible to media.
