No one wants to die. Even people who want to go to heaven don't want to die to get there. And yet death is the destination we all share. No one has ever escaped it. And that is as it should be, because Death is very likely the single best invention of Life. It is Life's change agent. It clears out the old to make way for the new. Right now the new is you, but someday not too long from now, you will gradually become the old and be cleared away. Sorry to be so dramatic, but it is quite true.
What does "as" mean in the underlined sentence? Can you paraphrase the underlined sentence?
The author is saying that the way that things are right now is the way that they should be. The author understands how death is an integral part of life and would not change anything is he had the power to do so.
