I dropped off this conversation much earlier due to the inability to get my
point across to John but I'd like to say your comment about both claiming to
be the original totally depends on the person who just underwent the
process. If I had undergone this, both would say, neither of us are the
original. Who I am is only a snapshot of that matter at that time in that
space and who I am now did not exist then and will not exist a moment from
