I come with a counter question: Is it given any proof that a Space Marine can die of old age? Dante has (supposedly) lived for over a millenia, while there was a Salamander on some planet (Novel: Salamanders by Nick Kyme i believe) who, with the help of a throne, had survived since the Horus Heresy.

Could it be that Space Marines only true cause of death is battle?
