The opponents of immortality focus on how supposedly immoral it is, and how everything is supposed to die - to make room for them, of course. First of all, there is no immortality. Something will eventually end your existence - by accident, by design or by your own hand, when you decide you want to control the moment it will happen, instead of being at the mercy of these former circumstances. Of course, a coward would never accept that truth. A coward would say that an immortal would shy away from danger. A coward would say that an immortal will be eventually left to emptiness and loneliness after untold billions of years. Who knows what will happen in billions of years? Or is it a disturbing assumption that you and you alone will get to be immortal? Be immortal for a single day first, then another, and so on. And in your greed and envy, do not deny the chance for longevity to others, who might be less scared of it than you are. Who might need more time to create something new. Who do not blindly focus on replacing their seniors in any of the, ultimately laughable, play-pretend hierarchies.
