I took a test years ago that showed me to be left brained. I was very disappointed because right-brained people were (according to the book the test was in) the creative, intuitive, artistic people, while left-brained people sounded rather rigid, staid, and boring. At least the book made it seem that way! :-)
I'm of the opinion that people are way to complex, dynamic in their knowledge and experience, and too tugged by demons and angels for there to ever be enough boxes to put us all in (figuratively speaking). :-)
