Dear Amy: Why are there left-handed people? — Kyle, Ann Arbor, Mich

Dear Kyle: It is a mystery why some people are left-handed, but there has been a lot of research to try to find out. Historically, left-handers were thought to be crazy and clumsy because they weren't like everyone else. Languages around the world seem to treat anything “left” as negative, whereas things “right” are positive. For example, the word “left” in Old English means “weak” and in German it means “awkward.” Being in your “right mind,” on the other hand, is a good thing.

Some scientists think that a certain gene causes people to be left-handed. If that gene is present, then the chance of a person being left-handed increases. What is certain is that the brain is split into two hemispheres. The right hemisphere controls the left side of the body and the left hemisphere controls the right side.

For a diagram of your brain and tons of fun information about being left-handed, visit www.left-handersday.com/tour4.html. The next time someone tries to call you lefties crazy, you can tell them that you're the one in your right mind.
