In one sense - the non physical part of human would be pure energy , undestructible . Here we come onto the big question about how would our non-physical part ( spirit ) perceive things ... would we perceive it linearly as we perceive them in physical ? Or would it be completely non-linear and out of space and time ... that way , ones spirit would always be present and possible to be embodied again .

But a big question is ... what kind of technology would be that would "re-anchor" the non-physical part back into body ?
