Identical structure and functioning

The concept of identical structure and functioning when used in the science of superimmortality (psychexistology) and conscious multiplicity discussions is the concept that, first, there is such a thing as a body. It is made of matter and energy. It is a biological system made of chemicals moving and functioning in complex ways with many different structures. It may have many different quantum states that are not determined at any one particular time. Another body that has identical structure and functioning to the first will have the same undetermined quantum states as the original body plus the same exact atoms in the exact same place in relationship to each other at each moment of time.
