I mean it's quite apparent at this point that death and decay (change) is a structurally inherent to the universe. Another word for change is time.
'Death' and 'life' go together just like 'backs' and 'fronts', and 'light' and 'darkness', 'insides' and 'outsides'. Language turns reality into caricature. Getting attached to nouns like 'life' is a recipe for frustration.
