It's a philosophical quirk, but it really depends on your existential and universal (philosophies / beliefs / religions). Things you must assume, basically, in order to make meaning from what is otherwise, pure logic (structural arrangement) and pure state (instances of that structure).
The idea that aging and death are undesirable is a complex phenomena to begin with. A rock does not care that the water slowly washes it away to shape it into a new form, yet humans have very discerning opinions on the matter across all phenomena they observe. Every explanation humanity manufactures seems to have some bias.
