Body can be compared with an automobile, but rather complicated than an automobile. And before starting our long journey on an automobile, we try to have sufficient knowledge about it. But starting our journey of life with a rather complicated, most ingenious, and most delicate machine ever made i.e. our body with no more knowledge of its structure than can be gained from gazing in the looking-glass; or of its needs, than a preference for filling up its fuel tank three times a day. More knowledge than this is often regarded as both unnecessary and unpleasant. Yet there are few things more important, more vital to our health, our happiness, and our success in life, than to know how to steer and how to road-repair our body-automobile.
Complicated our body looks to be, there are certain things about the plan and general build of it which are simple enough and can be and must be understood by all of us.
Very simply it is understood as
– It has a head end, where fuel supplies are taken in and where its lamps (eyes) and other look-out apparatus are carried;
– A body in which the fuel is stored and turned into work or speed, and into which air is drawn to help combustion and to cool the engine pipes.
– It has a pair of fore-wheels (the arms) and a pair of hind-wheels (the legs)
– It has a steering gear (the brain), just back of the headlights, and a system of nerve electric wires connecting all parts of it. It gets warm when it runs, and stops if it is not fed.
