[...] Since the 1970s, hundreds of studies have suggested that each hemisphere of the brain is home to a specific type of emotion. Emotions linked to approaching and engaging with the world -- like happiness, pride and anger -- lives in the left side of the brain, while emotions associated with avoidance -- like disgust and fear -- are housed in the right.

But those studies were done almost exclusively on right-handed people. That simple fact has given us a skewed understanding of how emotion works in the brain, according to Daniel Casasanto, associate professor of human development and psychology at Cornell University.

That longstanding model is, in fact, reversed in left-handed people, whose emotions like alertness and determination are housed in the right side of their brains, Casasanto suggests in a new study. Even more radical: The location of a person's neural systems for emotion depends on whether they are left-handed, right-handed or somewhere in between, the research shows.

    ..What if I'm proficient at everything? Does that mean I'm good with my right hand, left hand, and the one in the middle?

    Consider that if you ask around, everyone who happens to have that third arm that you speak about will declare proficiency in its use.

      Well, it's said that 10,000 hours of "practice" in anything will make you a world-class expert...
