How the Body Operates

This area is normally regarded with distaste. Why that is when we all function in the same manner and in many ways we do not actually have any control of what our body does is surprising. Unpleasant they may be but here are a few fascinating facts about the workings of you and me.

We all produce saliva, it is part of the digestive process and helps our bodies break down the food that our teeth so efficiently chew. However it is being produced all of the time, whether we eat or not and in an average lifetime enough saliva will be produced to fill one Olympic size swimming pool.

Have you ever been constipated? Well this fact may surprise you, but about 75% of human waste is water. Even though it may feel solid there is still a fair amount of liquid present. However constipation does generate waste which does not quite have enough liquid in it. So even though we urinate liquid it is also present in our faeces.

Following on nicely, did you know that 14 times a day is the amount of times the average person expels flatulence. Sometimes it can happen without even being noticed but often the trapped gas in the abdomen causes discomfort and pain and has to be released. If you feel that perhaps you are too refined to partake in such an activity, rest assured that when you are asleep then you are doing it.

Most people know that it’s impossible to sneeze with your eyes open. The body always involuntarily closed your eyes just at the moment of the sneeze. Have you every wondered why we have evolved this way? Well it could be because the air being expelled from our body flies out at over 100 miles per hour, that’s about 160 km per hour. Any germs present can go a long way on that blast, hence why we use handkerchiefs and put our hands up to our faces.

Even a cough can produce a 60 miles per hour gale. So although the germs don’t get a rocket launch like a sneeze they do get a flying start, hence why viruses are so virulent.

Earwax is a defense mechanism which protects the inner ear from dirt, fungus and bacteria, in fact anything small enough to go that way. Not only that but it also acts as the canal cleaner and lubricates everywhere it goes. So you may think that it is a disgusting smelly substance but it is crucial to the health of our ears.

Smelly feet are common because of the ability of the feet to produce sweat through their half a million sweat pores. They can produce up to a pint of sweat a day and because men have much more activity in the sweat glands down there then they are more likely to have shoes which may not be very ‘friendly’.

Your bladder is a very elastic type of organ. Normally about the size of a large grapefruit it will send signals that it needs to empty when it holds around 250 ml to 300 ml but because we are all built so well most bladders can actually hold up to 800ml. But by then you might not be able to run to the toilet.

Blinking is another thing that we all do, normally unconsciously, although sometimes we notice we are doing it. Women generally blink twice as often as men.
