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!

The 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.

This 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.

The 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.
