I am ostensibly right-handed.  I have a sister who is strongly
left-handed, and there are several others in my family who are
likewise.  I spent a great deal of time, as a child, with my
grandmother, who was from the "old country" and was superstitious.
She felt that the left hand was "evil".

As I grew up (right-handed), I discovered that there were numerous
things that I did better with my left hand.  I became a
"switch-hitter" when I played baseball in high school (unusual in
those days).  When I chose my career (I am a neurosurgeon), I
discovered that I was actually ambidexterous, and could perform
skilled hand movements with either hand.  This has been a great boon
to me (and to my patients).

I suspect that I was born left-handed, and was "switched" by my
superstitious grandmother (I asked her when she was still alive, but
she denied it).  I think that handedness is genetic most of the time
(in the absence of other "brain damage"); and that, if done early in
life, can be "switched" easily.  In my case, it proved to be
beneficial.


Best,

Bob
