Who will be next to go on 'Walking Dead?' Maybe it's you.

Like the ill-fated characters on AMC's "The Walking Dead," loyal viewers of the hit show have also been known to suddenly depart the realm for any number of reasons -- often having to do with the fatigue that comes with the zombie apocalypse show's inexorably pessimistic, permanently violent story arc. More than one person has told me they just ran out of stamina and quit watching.
