Some sources say around 30 million people in the United States are left handed. In 1992, August 13 became “Left-Hander’s Day” to celebrate and to raise awareness of the frustrations of left handers living in a right handed world. I have many friends who are left handed and I never really gave it too much thought. I've learned a little about the frustrations of the left handed world.
It's not all bad news, however. St. Lawrence University in New York conducted tests and discovered that there were more left-handed people with IQs over 140 than right-handed people. Some well-known left-handers include Albert Einstein, Isaac Newton, Charles Darwin, and Benjamin Franklin.
