Why are some people left handed?



A person who is left-handed primarily uses his or her left hand, more so than the right hand; a

left-hander will probably use the left hand for tasks such as personal care, cooking, and so on.

Writing is not as precise an indicator of handedness as it might seem, because many left-handed

people write with their right hand but use their left hand for other tasks.

"Because lefties do it right!" "Because left handed people are the only people in their right minds?"

Why are some people left handed?

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.

Left-handed people think quicker when using both sides of the brain


Researchers in Australia have found that being left-handed is linked with quicker thinking when

carrying out tasks such as playing computer games or playing sport. The study, published in the

journal Neuropsychology, shows that connections in the left and right-hand side of the brains are

faster in left-handed people.
