Some zombies eat, some don't. Don't know if that's a regional thing, or a variant of the disease thing.

The one's that "eat" will eat any flesh. Obviously, a lot of zombies have some freakish fetish with brains. Must be the prions or something. Past that, they'll snack on a nice freshly ripped off chicken wing, or a festering drum stick.

The one's that don't eat just tend to bite - usually at your eyes and neck. They love to bite out your throat and try to rip out your eyes.

Oooo! - Now I have Disturbed's "Down With The Sickness" stuck in my head!
