If you read the book parasite Rex, it will give you a better idea of what you are dealing with. Those little critters have the ability to control their hosts. It is amazing. Do not let this frighten you, however.
They are designed to do their thing, and that's it. We are infinitely more creative.

On the other hand, maybe it was just too much psyllium.
