Though it’s been previously suggested that zombies would probably not be able to smell anything other than their own rotting bodies, ZRS Researcher Seth Lipsky proposes that the undead may benefit from some form of postmortem super-smell. His argument strangely stems from a common side effect observed in users of psychedelic drugs.
Hyperosmia is a condition in humans that causes an acute increase in the ability to smell. It is often seen in patients with cluster headaches or migraines, but tests have shown that recreational use of LSD can result in the same or similar outcome.
“It’s commonly accepted that zombies are driven by their brains. Therefore, it stands to reason that a brain disorder affording the living a tremendous increase in their sense of smell may also be at work in the undead.”
Lipsky further points out that people with Addison’s disease, a disorder wherein the adrenal glands produce insufficient steroid hormones, are also inclined to suffer from Hyperosmia. Because zombies are likely not producing needed steroids with their limited body functions, a de facto Addison’s scenario could be at work.
So the next time you find yourself in a town full of hungry zombies, hiding out for them to pass by might not be such a good idea. If Lipsky’s theory is correct, they’ll be able to smell their dinner from miles away. And in this case, dinner is YOU!
