Amazing human being
The human body is just about as amazing as you can get considering all the functions it performs for each and every one of us, each and every day. Here are some amazing facts about the human body that you may not of known.
Of course we all know how important our heart is right? Did you know the heart has enough pressure to actually squirt blood 30 feet away. Maybe that is why we can feel our heart beating so easily.
Surprisingly the heart of a woman beats faster than that of a man, and is due in part to a woman being physically smaller than a man, and as a result less blood is needed to pump throughout the body.
So what would be the benefit of right-handed people over the left-handed people? Well amazingly on average right-handed people live nine years longer than left-handed people do. Considering that most machines and tools we use on a daily basis are actually designed for right-handed people, and so making the machines a bit more dangerous for left-handed people, and as a result thousands of accidents even deaths each year.
Would it surprise you to know that our stomach produces acid. Furthermore our stomach acid is so strong that it can actually dissolve a razor blade. Not so surprising is how our stomach lining is replaced every three to four days with new stomach lining, and each time it is dissolved it is due to strong digestive acids. So with these acids not only does it do its job with the food we eat throughout the day, but this same acid that our stomach produces is so strong that it can eat through many types of metals. That is strong! Amazing strength for our stomach.
Also in consideration for what is strong which of course are the muscles in our bodies, but probably not the muscles you would expect. Surprisingly the strongest muscle in the human body is the tongue. Our tongue works the whole day when we eat, swallow, and even talk, it's almost nonstop working. I recommend you not to lift weights with your tongue though.
Amazingly the body of an adult every day produces 300 billion new cells. Our bodies simply require energy to keep our organs working and running, and continuously repairing and building new cells.
What about a cold room? Sometimes the cold can be bad as in the cold room you sleep in. You actually have a better chance of having a bad dream if you sleep in a cold room. Scientists are not sure why, but if you do not like having nightmares then be careful how cold you have the room when you sleep.
Sexual relations happen about 120 million times a day about 4% of the population on earth. As a result birth rates increase in various places of the world. Should the birth rate be of any surprise?
Our eyes allow us to see the world around us, but our eyes from the day we are born always remain the same size, but what never stops to grow are our ears and nose they both continue to grow our whole life.
Our ears also produce more ear wax when we are afraid than when we are not. Studies have shown that the sticky substance that our ears produce is caused partly by fear, but the reason however is not clear
Our middle finger nail is the fastest growing nail between our hands and our feet, and the fastest growing nail of all is on the dominant hand, and still that fastest growing nail is on the middle finger of the dominant hand.
How many miles of blood vessels are there in the human body? There is estimated to be 60,000 miles of blood vessels in the whole human body. In comparison around the earth the distance is 25,000 miles.
Which one can humans do longer without... food or sleep? Well lets just say experiencing psychological changes, and personality changes that can become radical can happen only after a few nights without sleep. A person can survive without food for one or two months, so sleep is much more important for survival of the human body than food is.
We know our brain tells us when we feel pain, but can our brain actually feel pain itself? Your brain lets you know when you cut yourself, or if you burn yourself, but our brain itself is unable to feel the actual pain since it does not have any pain receptors.
