People have been conditioned down through History to believe that Humans are so very superior to Animals, therefore they don't get Parasites, and, if you live in the U.S. "Parasites are rare and usually come from Third World Countries" blah blah blah LOL!!!!!Ha ha ha ha ha!!!
The arrogance is hilarious! (Or is it ignorance, or both?)
People are Animals, they just need to face it. And ALL Animals get Parasites.
