Consciousness is a funny thing. It is a by-product of the enormous lump of neural tissue busily processing input from all our senses, and just simply managing the complexities of itself and the body. This includes a whole host of virtual senses that are themselves by-products of things like vision and our ability to recognize patterns. Our consciousness, the thing that makes me uniquely "Me" and makes you "You" is intrinsically tied to the body and the biological processes therein. As our bodies change, so do we. An adult is not a child, even if they do act like it occasionally.
