"Not that I can recall any of this, but my parents told me when
I began to learn to write, I broke my right-arm. Therefore forcing
me to use my left hand, thus I am left-handed. I don't know if my
broken arm made me left handed, or if I would have naturally been
left-handed, but from my point of view, left or right is not genetic."


There are a couple of tests that can help determine which you truly are:

1)Hold your finger up, line it up with a distant object, then quickly draw
your finger back to your eye while still watching the object. This will show
which is the dominant eye.

2)Have some one observe which shoulder is higher while you stand with your
eyes closed and your arms outstretched. The dominant side will tend to be
higher.

In Morocco it is extremely impolite to use your left hand for eating or even writing.
While there, I greatly improved my abilities with the right hand. I now eat with
either hand and can write passably also.

I wonder if being left handed had a survival advantage that counteracted the negatives.
Lefties tend to have stronger immune systems. It could be that there was a slight advantage
during epidemics. Other wise why would such a disadvantageous trait survive?

Somewhere I heard that lefties tend to be more accident prone. This is supposed to explain
why only 1 in 200 80 year old's are lefties.

A percentage of lefties are so because of either brain injury or extreme stress in infancy.
This may explain why a disproportionate percentage of institutionalize people are lefties.

Both the top and the bottom of the IQ spectrum are disproportionately represented by lefties.

Well I excelled in Math...Calculus 2, could have went higher if I wanted to. But I did lousy in other subjects particularly any language course...English, Spanish, German. I am horrible at those.

I am one of the converted.


Fortunately I'm able too use both hands for most tasks, though my writing is shocking, I find it more natural to use my left but I am forced too use my right and gets quite frustrating sometimes.
