left handed

9 out of 10 people, all over the world, are right-handed. True ambidexterity occurs in less than 1% of the population. Why does the world skew to the right? Scientists still don’t know.

Things like nipples and nostrils come in pairs on the outside of our bodies, but it doesn’t work that way in the interior: The heart and spleen, for example, normally form on the body’s left side, while the liver forms on the right; each lung has a distinctly different shape. We’re asymmetrical INSIDE.

Our brain halves are different too: the left side is more logical, while the right hemisphere is more creative and intuitive (although that pattern is reversed for lefties).

…something you wouldn’t guess: they’re SHY – Something we wouldn’t have guessed: people who are left-handed are more shy and easily embarrassed than the rest of us.

In recent research, more lefties than righties said “yes” to statements like, “I worry about making mistakes.”

But that doesn’t mean that lefties don’t have fun: Both righties and lefties said “yes” at equal rates to statements like “I often act on the spur of the moment” and “I crave excitement and new sensations.”

Scientists are fascinated by left-handedness. They know that being a lefty is genetic, so there?s no use trying to change. Scientists have discovered a gene which seems to make it more likely that you’ll among the 11% of people who are lefties.

In LiveScience.com, Andrea Thompson reports that lefties currently make up about 11% percent of the population, but earlier studies showed that only 3% of people born in 1900 were left-handed. Is this because they were forced to write with their left hand? Or are lefties having more children and passing on their genes more than righties?

Anne Strieber, (who is right-handed) was told by her neurologist that being left-handed is a higher stage of human evolution, because lefties use their ENTIRE brains to do everything, not just the opposite sides from righties, as they once thought. But sometimes, the right hand really may not know what the left hand is doing.

Scientists have learned that hand relies on a different set of sensory inputs to control its movement. In right-handed people, their dominant hand was found to be more dependent on vision for its guidance, while the left, non-dominant, hand was guided by body-based sensations from muscles, joints and skin.
