I think lefties have a better connection between brain hemispheres, but that is just a theory.
Not theory, it's true. On average, the corpus callosum is 11% larger than righties.
We share this with females, but have larger brains, too..score!!edit on 29-4-2012 by unityemissions because: (no reason given)
Of the seven most recent U.S. Presidents, four, including Barack Obama, have been left-handed, while a fifth is said to have been ambidextrous: Ronald Reagan, who was left-handed by birth, became president after he defeated left-handed candidate George H. W. Bush in the Republican primary election. Four years earlier, Reagan had lost the Republican presidential primary to incumbent left-handed President Gerald Ford. George H. W. Bush succeeded Reagan and later ran for re-election against left-handers Bill Clinton and Ross Perot. Clinton's second term opponents included Perot, and Bob Dole who had become left-handed when his right arm was paralyzed in combat 50 years earlier. Left-handed then-Senator Obama defeated left-handed Senator John McCain in his race for the presidency.

It was discovered, about 20 years ago, that in utero one of the baby's arms sticks out of the placenta and sort of pushes or strokes the amnioatic sac around. It appears - I don't know if there has been a thorough census of pregnancies for this - that approx 90% of the time it's the fetus's right arm that pokes through. I do not know if anyone has established that the dominant hand in childhood is that the same that was poking through in utero but it seems plausible.
Children who are ambidextrous, using either hand with the same ease, may be more likely to have mental health, language and academic problems than their peers, according to a new study.
48.9% (of exceptionally gifted and intellegent children) were ambidextrous at some period of their development.
