Are Left-Handers More Smarter?

Yesterday is August 13th, do you know what day is it? It just is international Left-Handers Day! Yes, no doubt, this “left-handed” is what you know “left-handed” – people who used to use the left hand. On August 13, 1975, a group of leftists in the United States established an organization called the left-handed international organization, envisioning the union of the world’s leftists together for the rights of left-handed persons. In 1976, the organization held a celebration and identified August 13 as an international left day. It is understood that about 6% to 13% of the world’s people are left-handed, and this figure is still on the rise.

Left-handers are more and more.
