Chances are, your father probably ingested tape worms to help him keep that girlish figure while still putting it away at the dinner table. Wasn't that huge in the 70's and 80's? That particular tapeworm was a mere cestoda, however, not a pork tapeworm or Taenia solium.
The point is, T. solium isn't your father's tapeworm. Pet ownership isn't about simply letting a parasite leach off your meals while you reap the slimming effects. When you open your body cavity for a T. solium infection, you're letting in a creature that really wants to get to know you. Not just your bowels, but also your muscles, eyes, spinal cord and maybe even your brain.
If your pet pork tapeworms do make it into your eyeballs, you might experience a detached retina. If they make it into your brain or spine, you also might have to put up with a case of neurocysticercosis. Depending on how many lesions take up inside your skull, you might experience symptoms such as confusion, headaches, attention problems, vertigo, swelling of the brain and sudden death.
Other selections: While you should never choose a pet parasite solely for the neurological side effects, you can also cloud your brain with a nice Malaria fog. If you're a cat person already, consider rooting around in the litter box for a little toxoplasmosis.
