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
People who are left handed use their right brain, which appears to help in geometry, and related subjects. There also appears to be a connection between lefthandedness and intelligence.
