I think that the product of the body functions are given by our hability to think, of a developed intelligence, in other words depents of the normal function of the brain. the human body functions, as talk, walk, run , eat and blogg are biologic, other wise, the soul do not belong to the body functions, it is untochabl, it is spiritual, something that we can not see it, and in any shapeit will help us to improve our self.
The soul during history, was an unusual and polemic subject.
