Do we only use ten percent of our brain?

Theory: We do not only use 10% of our brains

6/21 - I have been mislead. I guess I just heard somewhere sometime that we don't use all of our brains. I'm sure other people have heard this too. I just read these two interesting articles, please check them out:

German disputes Scientology claim of brain use

Do We Use Only 10% of Our Brain?

They both support evidence that we do NOT use only 10% of our brains.

But, just in case it IS true that we only use a fraction of our brain (and for posterity):

Theory: If we used 100% of our brains, then we would have the knowledge of God.

note: I do not mean to say that God is human or that any human can be God.
