Right or left?

I force myself to write a blog entry because I need to.

If the dichotomy of the brain's functions holds true (i.e., if the right part of the brain is truly more analytical than the left one, or is it the other way around?), then I need to use my "artistic" cerebellum--it's been a long time since I had last used it.

I have deprived myself of reading literature--in place of books, I have dwelt of mathematical equations, limits of a function, Newton's Laws of Motion, tangent lines, polymerase chain reactions, mRNA, the Watson-Crick model of the DNA....

I force myself to end this blog entry because I need to. I have dwelt more than five minutes writing this piece, and I have to get back to my books. I am exaggerating, of course, and so what part of my brain am I using now?
