August 13 is designated International Lefthanders Day by Lefthanders International. It was first observed on the 13th of August, 1976. As the name suggests, it is meant to promote awareness of the inconveniences facing left-handers in a predominantly right-handed world. It celebrates their uniqueness and differences, who are from seven to ten percent of the world's population. Thousands of left-handed people are discriminated in today's society, are forced to use right handed tools, drive on the right side of the road and even get harassed. International Lefthanders Day is made to end this discrimination. There’s also a more serious side to the day, which spreads awareness about the special needs of left-handed kids. Also, left-handers are far more likely to develop schizophrenia than right-handers, for reasons not well understood.
