Given the implications of ressurrection, how do we age mutants? Do we go by their Chronological Age or what is essentially their vessel age?
Say a mutant brain that had several lifetimes of experiences. It's pretty clear from Sins of Sinister that the mutant mind can hold a 1000 years of memories.
With several lifetimes of experiences, I suppose Apocalypse and Selene are in a similar situation. Would 1000 years of memories make certain phases in your lifetime feel so insignificant? And is it possibly a contributing factor to how non challant they are with other lives?
