Today happens to be Left-Handers Day, dedicated to all you weirdos who use funny-shaped scissors and golf clubs and stand on the wrong side of the mound in baseball games.
Not being a lefty myself, I don’t have a lot to say about it, but I do like the old phrase “Only left-handed people are in their right minds,” due to the way the different sides of the brain control their opposite sides of the body (the right side of the brain controls the left side of the body).
There’s all kinds of interesting studies about the corpus callosum and what happens when it’s partially or fully severed, enough to make a person very glad that regardless of whether he or she is a lefty or a righty, at least the two sides “talk” to each other.
If you’re interested in how different parts of the brain influence how we think, I highly recommend “Brain Sex,” which focuses on gender but also covers a number of other issues with brain parts, such as the left-right stuff. Quite interesting!
