Updated on January 15, 2013

Your brilliant body.

The human body is an amazing natural machine, made up of millions of cells and hundreds of parts, working thousands of functions all in harmonious reliance. For us to be in existence at all a multitude of intricate and delicate processes have to be functioning. The ability to breath, think, feel, sleep and do all the other other amazing activities within our ability, mean that certain mechanisms are needed for our bodies to work adequately.

The concept that I find the most extraordinary, are the functions and possesses that largely go unnoticed because they are involuntary, my heart beats, my ears hear, my eyes see, my lungs inhale and exhale, without any conscious effort on my part, I don't have to think about doing it, I take it so much for granted in fact that I don't even realize I'm doing things, when I am.

The human body is fascinating, just have a look at some of these facts.....

      This was very educational - I had no idea my ear had eight muscles in it, it is comforting that my thigh bone is stronger than concrete.

      Great list Wrenfrost, but you said we can only taste what our saliva can dissolve, then why do rocks taste so terrible? Just joking, one thing I know is our cells rejuvenate every seven years completely.

      The small intestine is larger then the large intestine.

      Now I am completely confused.

      Here is another fact for you.

      When men reach a certain age their waistline increases and their hairline decreases.

      They do not really lose hair it just relocates to places it had previously not been. Like the ears and back.

      No wonder we close our eyes when we sneeze. Otherwise there would be a lot of eyeballs underfoot. Great collection of body trivia, wrenfrost. Thanks for adding to our knowledge.

      "What a piece of work is a man, how noble in reason, how

      infinite in faculties, in form and moving how express and

      admirable, in action how like an angel, in apprehension how like a god! the beauty of the world, the paragon of animals" - Hamlet.

      My thigh bone is not feeling that strong anymore!

      Loved this great compilation of facts.

      Love and peace
