Left-handednesses
When we talk about left-handedness,we will first prefer to writing with left hand.But do you know,some left-handedness also use right hand to write.Maybe you are just a left-handedness,and you don’t know that.
OK,what’s a left-handedness exactly?To explain this,we should exam our brain first.Brain divide into two hemispheres,right hemisphere and left hemisphere.Each side hemisphere controls other side body.That means right hemisphere controls left body,and left hemisphere controls right one.A left-handedness is just a people have a stronger right hemisphere brain,so he or she would like use his or her left body to do most things.For example,walking in dark night,they also use their left feet to touch the unknown field.Unforninately,in tradition,children all are told to use right hand to write,so,lots of internal left-handedness also use their right hand to write.
Look at our bodies.They are symmetry,why most of people prefer to work with right part,not left part?Anthropologists found some interesting things.In the ancient world,about 8000 BC,they found the tools that make from our ancestors,were kind use with any side hand.But after 3500 BC,the tools became to only kind use with only one hand,and most of them were kind use with right hand.Why human choose right side.No one can explain it exactly.But after all,our ancestors made one choice:let’s practice right side more.
Today,right-handedness are surely more than left-handedness.But you are sure that you are not left-handed even you use your right hand to write?There is a simply test.First,relax.Second,get a pen,and circle on a paper with one hand.Three,another hand.If you circled all in clock-side,maybe you are a left-handedness in fact.
