But the body remains. Vacancy does not mean death. In fact, it means a different form of hungered life… It is a body with organs that has a complicated relationship with its cerebral partner. That body strapped into the car will suffer and be crushed on impact. The body that walks into traffic suffers a similar fate.
And as the mind continues to accept that this vulnerable corpse must be protected, the world around us will shift to accommodate the zombie multitude.
