Carbon tax protest at Nova Scotia-New Brunswick border | SaltWire #newbrunswick #novascotia #rallyWASHINGTON - What do Lady Gaga, Barack Obama, Bill Gates, Paul McCartney and Justin Bieber have in common with Ronald Reagan, Jimi Hendrix, Judy Garland, Fidel Castro and David Bowie? They are all left-handed, a trait shared by roughly 10% of people.
"For example, most people have left-hemisphere dominance for language, and right-hemisphere dominance for tasks that require directing visual attention to a location in space," said neurobiologist Clyde Francks of the Max Planck Institute for Psycholinguistics in the Netherlands, senior author of the study published on Tuesday in the journal Nature Communications.
The two cerebral hemispheres start to develop differently in the human embryo, though the mechanism has remained unclear. Over the centuries, many cultures disparaged left-handedness and tried to force lefties to become right-handed. In English, the word"right" also means"correct" or"proper." The word"sinister" derives from a Latin word meaning"on the left side." And a"left-handed compliment" means an insult masquerading as praise.
