By what measure is a (hu)man?: On mutants and vampires...

[Coolguye]

If you actually read my post you'll find that, in the second-last block of text, I talk about zombies.

They're sorta hand-waved away as 'obviously not alive', but drugs affect them (pulse), and their temp isn't off-kilter (if my handful of experiences as a player zombie are accurate). The only way they're 'obviously not alive' is their coloration and their groaning, and the same arguments could be applied to vampires with their starlight vulnerability (pigmentation and unearthly screeching).
