Do our brains / bodies fallow the laws of physics?

Of course our brains follow the laws of physics. You take out the occipital cortex, you can't see. You take out the limbic system, you have no emotions. You take out Broca's area, you can't talk. So it stands to reason that consciousness is physical process, and those who don't agree with that are always going to be the ones who believe in the supernatural (ie.religious types). In this sense, everything has an original cause, and our decisions therefore are never made outside of the context of our memories, environment, personal histories, and genetic predispostions. That is not to say that everything is preordained, but that every person does not have an infinite range of choices, because there are only certain kinds of choices you could ever make based on our unique cirstances. So free will as it's been proposed by those who believe that the mind exists outside the physicial structure of our brains is really a fallacy, and not the kind of free will any of us would want to have anyways.
