As a left handed person I found this article: 'Left handed' coiling snails survive more snake attacks by the BBC's Victoria Gill, pretty interesting. I love hearing stories of left handed superiority. According to this article, a certain species of snail that has shells that coil either clockwise or counterclockwise is experiencing natural selection due to their shell orientation.
Due to the way snakes suck a snail out of its shell, and the way snakes jaws are formed, only snails that have shells that coil to the right are susceptible to predation. Snakes just can't suck a snail out of a shell that coils to the left. Ha! Left handed dominance! According to researchers, the snails are starting to branch off into their own species, because eliminating the threat from snakes has been really beneficial for their population.
I'd also like to take a moment to point out that the idea that left handed people are sadistic is a myth. The word sinistrality is used to refer to left handed people because it is derived from the Latin word sinestra which means left handedness. Nothing to do with demons, sorry.
I take pride in being left handed but it can be a pain at times (like when I was learning how to write). Apparently left handed people have a shorter life span than right handed people based on accidents caused by using tools, and equipment designed for right handed people. I guess I better watch out.
But I do have good company in my left handed ways: Ronald Reagan and Bill Clinton (the likable Presidents!) Joan of Arc, Leonardo da Vinci, Michelangelo, Paul McCartney, Charlie Chaplin, Robert DeNiro, Cary Grant, and Marilyn Monroe (lots of others too I just found these the most interesting.)
