No-one has come up
with a definitive reason for WHY some people are left-handed, but about
10% of the population around the world are. No gene for left-handedness
has been identified, but it does seem to run strongly in families.
The brain is
"cross-wired" so that the left hemisphere controls the right handed side
of the body and vice-versa and hand dominance is connected with brain
dominance on the opposite side - which is why we say that only
left-handers are in their right minds!
(Chart reworked by DennisQ545@comcast.net)
left hemisphere (RIGHT HAND CONTROL) controls Speech, Language, Writing,
Logic, Mathematics, Science, this is the LINEAR THINKING MODE. The right
hemisphere (LEFT HAND CONTROL) controls Music, Art, Creativity,
Perception, Emotions,Genius, this is the HOLISTIC THINKING MODE.
brain dominance makes left-handers more likely than right handers to be
creative geniuses. This is supported by higher percentages of left-handers
than normal in certain jobs and professions - music and the arts, media in
general. Left-handers are also generally better at 3-dimensional
perception and thinking, leading to more left-handed architects than
normal. Left-handers are also usually pretty good at most ball sports and
things involving hand-to-eye co-ordination.
view that left-handers are clumsy and awkward is not down to their natural
abilities, but being forced to use right-handed tools and machinery which
is completely back-to-front for them.
