The human being has many innate or inherit physical qualities existing in or belonging to us, through our genetic makeup as a species, from birth. This is shown in our body make up of being a primate and the physical appendages that make up this physical being. Some believe we are created this way, some believe we have evolved to the being we are now. Whatever way you believe we came about, it is simply true that we are a bilateral being, that has a large self aware brain, two feet that allow us to stand upright, two hands which through the thumb, is used to grab/grasp objects and the combination of this thinking mind with the hand structure, allow us to logically manipulate said held objects (tools) to multiply our force. (Don’t forget our voice box manipulation but that’s another story).
These physical attributes have an enormous effect on the way we move and also affects the way we struggle and fight for survival.
Dominance Of One Side
The human body is bilateral or two sided and this body moves through Bi-Pedal Motion. This body has one brain. This brain is divided into two halves/sides and this brains halves control the movements of one side or the other side of the body. One half or one side of this brain has evolved to be dominant, which makes one side of the body to be leading or dominant. One side of the body being dominant, will often enable this side to obtain more strength through exercise of preferred use.
Simply, humans will prefer one side to do things first and this is usually through use, the stronger side. This divides the sides of the body into the ‘Primary’/‘Dominant’ (the stronger) and the ‘Secondary’/‘Subordinate’ (the weaker or the follower).
