If the cells in our body (including brain cells) are replaced every 7 years, then in a sense we should be completely different individuals than we were 7+ years ago. But to us, we sense the sameness in consciousness throughout our life. How can that be? My belief is that it is the information we possess that gives us consciousness. This information conforms the cells (and molecules and atoms) to particular patterns and makes us who we are. So it would seem that your conscious could be duplicated (as long as it does not violate Pauli Exclusion principle) if enough information was collected.
