We are dying, we are dying, we are all of us dying
and nothing will stay the death-flood rising within us
and soon it will rise on the world, on the outside world.
Not everyone wants to live forever, but every culture has always desired immortality in one way or another. Humans have always believed in the possibility of another life, of a second act. We've also always hoped that there might be a way to avoid dying. The term "cultural-universal" is a complicated one, but I've heard it come up on numerous occasions while researching immortality.
