Wouldn't an actual zombie apocalypse be super-easy to defeat?

How long can a person survive without food or water? Days without water, a month without food, broadly speaking. Why should a zombie be different? Muscles take energy to move, all that moanin’ and shufflin’ takes energy to do. There’s no such thing as an energy-free shambling. Even if a zombie was ten times more effective at metabolising their energy reserves (metabolism really isn’t very efficient, frankly), they’d all run out of power within a year’s time.

I have the same thought. Ok, they’re low energy, so maybe they last a year. But on TWD some of them have been shambling around for 10 years now.

You also mention “rotting away.” We have actually seen zombies with maggots infesting them, so they are not immune to decay. Exposed to the elements, they should be in the same condition as any other 10 year old corpse, that is, a bunch of bleached bones.
