i am left handed. cheers! here's a funny thing. i used to work with someone who was pseudo-left handed. he was born Situs inversus. which means that all of his asymmetrical structures are mirror reversed. he was unaware of this until getting appendicitis, on the wrong side. this occurs in about 1 in 10,000 people.
so, he is left handed, but his brain and therefore his handedness, is reversed.

great post.
