World Marks International Left Handers Day

International Left-Handers Day was first launched in 1976 and it is celebrated annually on August 13.
The day was introduced by American Dean R Campbell. Despite left-handed people now being thought of as highly intelligent, the English word left comes from the Old English lyft, meaning idle, weak or useless.
Dean R Campbell, founder of the Left-handers International, wanted to raise awareness of the difference of living in a right-handed world. Hundreds of left-handed people have to adapt to use right-handed tools.
Campbell was also keen to highlight the special needs of left-handed kids.
It is thought that left-handed people may be more likely to develop schizophrenia because of their enhanced creativity and imagination.
Around seven to ten per cent of the world's population are said to be left-handed. It has been reported that around 10 per cent of the UK population write with their left-hand.
Studies have linked a left-hand preferenc with increased mathematical skills. Left-handedness is sometimes called sinistrality.
A left-handed boxer who leads with his right hand is called a southpaw, but it is a term used for anyone who is left-handed.
Left-handers, including Prince William, former US President Barack Obama and Greek philosopher Aristotle, are said to be more intelligent and talented.
