I just read this article (mumble..mumble..Jack..mumble..mumble..) and thought the points it made might make an interesting discussion among the left- and right-handers on Volconvo. (I'm just assuming we're a mixed bunch). Basically it's saying that characteristics of left-handers include being more fearful, more angry, more inhibited, and associating "left" with good. The final point about left-handed politicians having an advantage on tv is interesting in light of Obama being left-handed.
5 surprising facts about left-handed people - The Week
Famous left-handers include Fidel Castro, Queen Victoria, Henry Ford and HG Wells. Both Prince Charles and Prince William are left-handed, and this is in line with a suggested genetic predisposition.
]http://www.indiana.edu/~primate/left.htmlResearchers who study human hand preference agree that the side of the preferred hand (right versus left) is produced by biological and, most likely, genetic causes.
Individuals with the C gene will have a 50 percent chance of being right-handed and a 50 percent chance of being left-handed. These theories of hand preference causation are intriguing because they can account for the fact that the side of hand preference of individuals with the C gene (most left-handers and some right-handers) can be influenced by external cultural and societal pressures, a phenomenon that researchers have documented. These theories can also explain the presence of right-handed children in families with left-handed parents and the presence of left-handed children in families with right-handed parents. If the familial genetic pool contains C genes, then hand preference becomes amenable to chance influences, including the pressures of familial training and other environmental interventions that favor the use of one hand over the other. The proposed genetic locus that determines hand preference contains an allele from each parent, and the various possible genetic combinations are DD individuals who are strongly right-handed, DC individuals who are also mostly right-handed, and CC individuals who are either right-handed or left-handed. These genetic combinations leave us with an overwhelming majority of human right-handers and a small, but persistently occurring, minority of left-handers.
What causes some people to be left-handed, and why are fewer people left-handed than right-handed?: Scientific American
InternationalLeft-handers Day, incidentally, is 13 August.
What do you think, do these qualities apply to you or people you know?
