Why are some people left handed?
"Because lefties do it right!"
"Because left handed people are the only people in their right minds?"
This question is definitely not a no-brainer.
Two theories predominate in the debates that rage on as to why a mere
4% o the population is left-handed. Most authorities agree, to the
relief of many a mother of a left-handed child, that if the child
prefers using the left hand, and functions well with it, there is no
need to correct this "condition."
One theory centers on the two halves of the brain, i.e. the left half
and the right half, each of which functions differently. Medical
science believes that the left half of the brain predominates over the
right half. The stem of this theory is the fact that nerves from the
brain cross over at neck-level to the opposite side of the body, and
nerves from the other side of the brain reciprocate. The end result is
that the opposite sides of the body are supplied by the opposite sides
of the brain.
The predominant left half of the brain, which graciously supplies the
right half of the body, theoretically renders it more skillful in
reading, writing, speaking, and working, and makes most people
right-handed. "Lefties," however, are the product of an inversion,
whereas the right half of the brain predominates, and they work best
with the left side of their bodies.
Theory number two trickles down to the asymmetrical nature of the
body. Examples of the asymmetry, which flows from head to toe, are
that the right side of our faces differs slightly from the left, that
our legs differ in strength, or that our feet vary in size. One aspect
of this asymmetry is that for most people the right hand is stronger
than the left.
There is no doubt that all exist in a "right-handed society," which
manufactures most basics, including scissors, doorknobs, locks,
screwdrivers, automobiles, buttons on clothing, and musical
instruments for the 96%. Left-handed people compensate for this
snobbery of sorts, by being members of an elite society, which
includes many of the greatest geniuses, including Michelangelo,
Leonardo da Vinci, and The Useless-Infomaster.
