Personal identity

Personal identity is the philosophical issue of determining whether two mental states[?] belong to the same person, whether a person exhibits continuity through time, and whether a person can switch bodies or characteristics and memories with another person and retain his continuous consciousness.

For example, imagine that after your death there is someone, in the next world or in this one, who is a bit like you. How would that being have to relate to you as you are now in order to be you?
