People are also left-footed and right-footed. Usually one eye is stronger than the other, so people can be left-eyed and right-eyed. And even stranger: pay close attention to your friends' faces. Really stare at them, watch closely when their lips curve into smiles. You'll see that people are almost always strongly left-faced or right-faced. One side is usually much more expressive than the other. In fact, if you mirror the two sides of a person's face to create a left-composite and a right-composite, you'll find yourself looking at two completely different people.
Connections between the left and right hand sides or hemispheres of the brain are faster in left-handed people, a study in Neuropsychology shows.
The fast transfer of information in the brain makes left-handers more efficient when dealing with multiple stimuli.
Experts said left-handers tended to use both sides of the brain more easily.
Why do old tales always associate the left with being not so good?
