Who ever use left hand to wirte ?

Huh? Writing with pencil and paper i remember those times.

Using the left hand ? So cool ! I have ever seen someone who used left the hand. It appeared not inconvenient for him.

Out of the whole world, roughly 12% of men and 10% of women are left-handed. If both parents of a child are left-handed, there is approximately a 26% chance of that child also being left-handed. One writer, Chris McManus, has written: "Studies in the U.K., U.S. and Australia have revealed that left-handed people differ from right-handers by only one IQ point, which is not noteworthy ... Left-handers’ brains are structured differently from right-handers’ in ways that can allow them to process language, spatial relations and emotions in more diverse and potentially creative ways. Also, a slightly larger number of left-handers than right-handers are especially gifted in music and math. A study of musicians in professional orchestras found a significantly greater proportion of talented left-handers, even among those who played instruments that seem designed for right-handers, such as violins. Similarly, studies of adolescents who took tests to assess mathematical giftedness found many more left-handers in the population."
