Left Handedness...

It is believed that lefty-s are apparently more creative and intelligent. But I would definitely disagree because I see way too many left handed people here in the UK and most of them are NOT more creative nor are they more intelligent than I am. LOL. So basically that is no fact! Its weird that there's so many left handed people here. Its like, almost everyone is a lefty. I still wonder how and when did you choose to use your right or left hand or are you really born with it? Cos I know a friend that could write with both hands. Hmmm...
