"Despite being a rather unrealistic scenario, the thought of a zombie apocalypse is something that ties into at least two of humanity’s underlying fears.

As a collective group, we always worry about what we’re being injected with at hospitals and doctor’s offices, and for good reason. However, with that being said, it’s unlikely that a dangerous serum would make it through today’s rigorous quality control efforts."
