Wouldn't their flesh (and brains) eventually desiccate and decay? Once all their flesh fell off and the tendons rotted away, wouldn't their bones just fall apart?
(Kind of like the Terminator movies. Once all the robots killed all of humanity, would they just stop and freeze where they stood?)
According to the authority in modern-classic (Romero-esque) zombie folklore, Max Brooks, a zombie has no metabolism outside of the brain. The Z-Virus, keeps the brain going, and the body continues to rot and wither until it turns to jerky... This is all of course physically impossible, since you need muscles to move...
