Being Left-Handed
No-one has come up with a definitive reason for WHY some people are left-handed, but about 13% of the population around the world are, and it is thought to be genetic - it definitely runs in families. Researchers have recently located a gene they believe "makes it possible to have a left-handed child " so if you have that gene, one or more of your children may be left-handed, whereas without it, you will only have right-handers - sorry! The good news is, that if you are left-handed yourself, you have that gene and will pass it on through the generations!
The way the brain works is incredibly complex, but this simplified explanation will give you some understanding of where our left-hand dominance comes from. The brain is "cross-wired" so that the left hemisphere controls the right handed side of the body and vice-versa and hand dominance is connected with brain dominance on the opposite side - which is why we say that only left-handers are in their right minds!
The left hemisphere (RIGHT HAND CONTROL) controls Speech, Language, Writing, Logic, Mathematics, Science, this is the LINEAR THINKING MODE.The right hemisphere (LEFT HAND CONTROL) controls Music, Art, Creativity, Perception, Emotions, Genius, this is the HOLISTIC THINKING MODE
Effects of right brain dominance
This brain dominance makes left-handers more likely than right handers to be creative and visual thinkers. This is supported by higher percentages of left-handers than normal in certain jobs and professions - music and the arts, media in general. Left-handers are also generally better at 3-dimensional perception and thinking, leading, for example, to more left-handed architects than normal. Left-handers are also usually pretty good at most ball sports and things involving hand-to-eye co-ordination.
The view that left-handers are clumsy and awkward is not down to their natural abilities, but being forced to use right-handed tools and machinery which is completely back-to-front for them.Some researchers claim that we are more intelligent and eloquent that our right-handed counterparts. In tests conducted by Dr. Alan Searleman from St Lawrence University in New York, he found that left-handers can be considerably more intellectually gifted.
There were more left-handed people with IQs over 140 than right-handed people - which is the "genius" bracket. This is perhaps why there are more "lefties" in creative professions - such as music, art and writing - and more left-handed astronauts and leaders than would be expected.
