Just to be clear, brain eating worms do exist. I understand that you can come across them in South America.
A few years back, Phoenix had a city councilman who climbed out his sunroof on top of his moving car on Camelback road and did a swan dive into the base of a palm tree and died. It turned out he had a brain worm he had picked up while vacationing in a remote region of Mexico. True story.
