There are 3 times more left-handers among men than among women. One answer might be basic morphology. Some studies, the researchers note, have found that left-handed and ambidextrous people have larger corpus callosums—brain regions that connect the two hemispheres—than right-handed people, which might be linked to differences in brain development between men and women.The scientific explanation for this phenomenon has still not been found. Researchers at the Australian National University found that left-handed people can process larger volumes of information than right-handed people.
