Our brain is undoubtedly the most powerful component of our body, but I do not mean there is anything less important. Every bit that makes up our anatomy is as significant as those which are very obvious like our eyes, or nose, or mouth. Here are some trivia about this most incredible creation in the universe.

In our brain alone, it is amazing to note that even though it seems to just dwell in a very small fraction of the head, there are 100 billion of brain cells responsible for it to function so remarkably, whether one is stupid or highly cerebral, everyone is composed of these useful cells. However, we lose around 100, 000 brain cells everyday.  Don’t worry, that figure is mathematically insignificant to the total number of brain cells that we have.

Our body has a total of 50 trillion cells, and 3 billion of these die everyday. Again, it’s not a reason to panic either because most of the cells that die are replaced quite immediately.  In fact, 10 billion new white cells are made each day which help fight infections and microbes.

You might have heard about the strength of Hydrochloric acid in your chemistry experiments. But believe it or not, our digestive system produces an average of 2 liters of HCl daily. Would it not scald our stomach walls then? Fortunately nope, because as some of the cells die, around 500 thousand cells in our stomach lining are replaced every 60 seconds.

If you think carbon is toxic, think twice since our body has enough of that element to make about 900 pencils. We do have fats to produce 70 average sized candles, more than enough phosphorus to make 200 match heads, and iron to create 3.0 inches nail.

On the average, a person blinks 20,000 times a day except when one has some blinking disorder.  We discharge an average of 2 liters of gases from our intestines in the form of either burps or bad wind (fart).  Daily, our hair grows by about a half of a millimetre, while our mouth could produce more than 37 thousand liters of saliva in a lifetime.  A human fingernail grows by 0.05 cm every week, which is four times faster than the toenails.

Our body’s nerve cells transmit messages at the speed of 290 km per hour. In cold places, a person loses about 0.5 liters of water every day through the sweat glands, but in warm climates a person may discharge as much as 13 liters a day. There is one bone in our body that is not connected to any other bone called hyoid bone, a U-shaped bone just at the base of the tongue.  Our skeleton makes up one-fifth of our total body weight, and the skin weighs up to 4 kilograms, depending on the person’s size.

Our eyes is the only part of the body that do not grow as we grow, and you might be surprised to know that we do have tails too, measuring about 1 to 2 inches long, which is located at the end of the spinal cord – called coccyx.

    so that is why small children have big eyes! never thought of that, very interesting:-)
