Life holds many frustrations for left-handed people – from the everyday
items designed for right-handers to folklore saying they are in league with the
devil.
So perhaps it is the result of dealing with such adversity that, according
to researchers, they are angrier than the average person.
Researchers found that among lefties, the two hemispheres of the brain
communicate more with each other so have more interaction with the parts which
produce negative emotions.
Everything from can openers to garden tools to knives and scissors tends to
be designed without taking them into consideration.
Many generations of left-handed schoolchildren were forced to write with
their right hand. They have endured centuries of stigma that says being
left-handed is evil or bad luck.
And they are often associated with clumsiness and awkwardness.
The study, led by Ruth Propper, a psychology professor at Merrimack College
in Massachusetts, found that the halves of the brain in those who are lefties or
ambidextrous are more interlinked.
This makes them more moody, research published in the Journal of Nervous
and Mental Disease found.
Previous studies have shown that 'lefties' are more prone to negative
emotions.
Many of the world's leaders and stars are left-handed, with some known for
being hot-tempered.
One famously grumpy 'leftie' is Bob Geldof, who achieved fame thanks in
part to swearing during TV coverage of Live Aid.
Another is tennis legend John McEnroe, who is as famous for his tantrums as
his successes.
Current world leaders who are left-handed include Barack Obama and David
Cameron.
But Lauren Milsom, owner of Anythinglefthanded.com, which sells goods for
left-handed people, said: 'Left-handed people just get on with it and do not
complain that much.
'We just deal with a world designed for right-handers.'
