Think about the human body. What is 5 + 5? Did you know that it took 10 watts of power to complete this simple task? Most light bulbs are 100 watts of power to light a room. A person uses one-tenth of a 100 watt power to read, to compute and comprehend these words. A computer as powerful as the human brain would require 1 gigawatt of power.

The following are a few other functions your body accormplishes:

The Brain is a complex mechanism.

1.  Did you ever wonder why your sweet teenager behaves differently when he or she reaches puberty?

The brain's structure changes during the teenage years.- according to neurologist, Jay Giedd, the brain system that regulates impulse and emotions are not fully developed until a teenager reaches the age of 18.

Senses accomplish amazing feats.

2.  The sense of time is what our mind perceives. Albert Einstein oft quoted explanation in his Theory of General Relativity: "When a man sits with a pretty girl for an hour," said Albert Einstein, "it seems like a minute. But let him sit on a hot stove for a minute, and it's longer than any hour." Latest research call this “time dilation” illusion. It depends on many different stimul the brain experiences.

iReproduction facts are straightfoward.

3.  All babies are born with blue eyes. It is melanin with the help of ultraviolet light that determines the final eye color..

Internal Organs are ignored until they start giving us problems.

4.  It is the stuff of advertisements: Do you suffer from acid indigestion? The acid in the stomach is hydrochloric acid. It helps break down ingested food. That is not all it breaks down. It is also strong enough dissolve a razor blade, or a nail. This leads one to wonder why the acid does not burn through the stomach.

5.  Stomachs have a lining of mucus. This Mucosa secretes bicarbonate-rich coating to the lining. The alkaline counteracts the acid and neutralizes it.

6.  Adrenal glands change throughout a person's life. The adrenal glands are above the kidneys. They are responsible for releasing stress hormones. A seventh month fetus's gland is the size of kidneys. After birth the glands continue to shrink. By old age, they are barely noticeable.

Miscellaneous, but, interesting facts about the human body that are fun to know.

7.  What is a philtrum? It is the little indentation between your lip and nose. Scientists are not sure why humans have it, but it is suggestive of the thinness or thickness of a person's lips.

8.  Memory is affected by body position. Where you are, how you are placed in your environment triggers memory. A past remembrance may give you a deja vu (a feeling of “knowing”).

9.  A person cannot tickle themselves. A person cannot feel it. The brain nerves anticipate the movement from the person.

10. If you commit a crime do not lick anything. A tongue print is as individual as a finger print.

The human body is amazing. There are many fascinating facts beyond the few presented here.
