Anyone who's seen a zombie movie knows this is the logical conclusion. I just hope the zombie white blood cells in my head are like the zombies from Night of the Living Dead, and not like the ones from 28 Days Later. I hope the zombies outside my head are like the ones from NotLD too, for that matter because if the undead are capable of sprinting I'm going to have to re-evaluate my odds of survival by moving them in a disheartening direction.
