Yes - it's today!
[quote:3aa7nfwr]August 13 is designated International Lefthanders Day by Lefthanders International. It was first observed 13 August 1976. As its 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 difference, who are from seven to ten percent of the world's population.
[quote:3aa7nfwr]Left-handedness is the preference for the left hand over the right for everyday activities such as writing. Most left-handed people exhibit some degree of ambidexterity. Left-handedness is relatively uncommon; 90 to 93 percent of the adult population is right-handed.
