...This question has many different sides to it. First of all what does immortal mean? Are you speaking of absolute immortality or do you admit different degrees? If for instance after the death of the body something remains which lives for some time preserving its consciousness, can this be called immortality or not? Or let us put it this way: how long a period of such existence is necessary for it to be called immortality?...
Thank you again Teo for this very interesting topic.
