Strattera, your post raises a whole set of fascinating questions. There are enormous practical difficulties for a person who does not age to move through our society without being identified. I think we’ve already established that personal security would be of immense importance to such a person: they have eternity to lose, whereas we have only a finite life span at risk. But the current era makes anonymity difficult. It appears that the person you and Flyss met has taken the approach of acquiring great power, as opposed to “the Aussie,” who seems merely to hide.
You also raise an interesting biological question. If the aging clock is disabled, or slowed, would that in some way allow regeneration of damaged tissue? Certainly, if this does not happen, one would expect an immortal to gradually accumulate wear and tear — and would that include such things as arthritis? I’ll need to check with a biologist friend of mine. – Stephen
