The fear of death is ultimately the fear of living. Perhaps we reasonably believe that death is not an event. Not an event we will ever experience - we will never experience our own death as we have not experienced our own birth.
How do children talk about death? They start talking about it from a very early age. They often mention it in connection with an animal. All of you have witnessed how children react when they are first confronted with death. They say, "It does not move at all!" And we explain to them, "Because it is dead." "What does it mean?", they ask you. And you don't know how to reply.
