Left-Handers’ Day is celebrated worldwide on August 13. The left-handers’ primary distinction from right-handers is that they use more of their right cerebral hemisphere, responsible for image, visual space and sensory perception and intuition, in their everyday life. That’s why a lot of artists, composers, musicians and poets are left-handed. Actress Marilyn Monroe, who became an American sex-symbol, opens the photo gallery of left-handed celebrities.
