And we call it crazy monkey sometimes. And we are making a song about it, and the crazy monkey is the brainstem. The brainstem, the primitive brain, is very able to direct... It's about to fight, to flight, food, to fuck and to freeze. Very primitive. But it's like a reptilian brain. It only reacts. It doesn't think. But because of our thinking, we are so dominated by our thinking, it doesn't get the right blood flow.
