Ask any left-hander, they will say they make better lovers…and in a way this is true because a left-hander uses the right side of the brain. A right brained individual is artistic and sensitive, meaning that they are, in many ways, more nurturing.
Left-handers are also better typists because the most used keys are on the left side of the key pad. They also tend to be better bowlers, boxers, tennis players, and baseball players.
At one time it was believed that left-handedness was unnatural, so parents and teachers would go to great lengths to “force” the leftie to use his right hand. This often produced an individual who could use both right and left hands, but as they can tell you they never “stopped” being left-handed. As the popular phrase goes “they were born that way.”
About ten percent of the general population is left-handed, and a higher percentage of these people seem to have auto-immune diseases, compared percentage wise to the rest of the population. It was shown in test studies that 25% of people who had inflammatory bowel disease were left-handed, a much higher ratio than the rest of the population.
One controversial theory suggests that left handers immune system problems may have started in the womb. The theory goes like this: An excess of the male sex hormone testosterone at the time of fetal development causes retarded growth in the left hemisphere of the brain, which accounts for the left-handedness and also suppresses the thymus, an immune system organ.
According to studies, it also seems as if left-handers are more sensitive to drugs that act on the central nervous system as well. In this study the brains electrical waves were greater than their right handed counterparts. Left- handers have a stronger reaction to anti-depressants, anti-histamines, analgesics, and anti-anxiety drugs.
There is also a lot more left handers that have high I.Q’s, so I guess there is a trade-off. They suffer more health maladies, but they seem on average to be smarter than the rest of us.
from my perspective, the left-handers deserve the reward of having a high I.Q. because they are unique, and they have to live in a right handed world. I mean, to them scissors cut the wrong way, corkscrews turn the wrong way, and using a power tool is a threat to their life.
The good news is that left handers are better able to use their right hand, than right handers are able to use their left hand, because they have had to adapt in a right-handed world. There is also nothing to indicate that left-handed people die sooner than anybody else.
Here is a list of a few “famous” left-handers:
Joan of Arc
Alexander the Great
King George ll
King George Vl
Jack the Ripper
So, what causes left-handedness? Although theories abound nobody really knows for sure, but it does seem to have a genetic component. If both parents are left-handed they have a 26% chance of having a left-handed child, a 9% chance if both parents are right handed, and a 19% chance is a child has both a right and left handed parent.
So, I guess all we can do is enjoy the artistic and sensitive nature of our left-handed brothers and sisters.
