In the human population, left-handers comprise about 10%. In the animal world, the ratio of righties to lefties is about 50/50.
Since lefties tend to be right-brain dominant, left-handers are represented in the creative arts at over twice their ratio as in the general population.
Some professions which have a far higher representation of left-handers include: architecture, law, mathematics, wait staffing, acting, and comedy.
Communication between both sides of the brain tends to be higher among lefties. This results in a thicker corpus callosum, the link between the right and left hemispheres.
Left-handers have a greater tendency toward dyslexia.
The term "ambidextrous," which describes a person who is equally capable with either hand, literally means "one who is right-handed with both hands."
In the middle ages left-handers were burned at the stake as witches.
There are significantly more left-handed men than lefty women.
Handedness, like speech, is not apparent at birth but appears gradually as the child grows.
Baseball parks were built so the setting sun shone into the right fielder's eyes. Thus lefty pitchers threw toward the west with their "south paws."
Lefty Albert Einstein once said: "Imagination is more important than knowledge."
