half of all humans carrying mind-control parasite!
You all know I love sensationalistic headlines like that one. Toxoplasma gondii parasites live in the stomach of cats. The eggs and up being eaten by rats, causing them to be less afraid of cat urine, and other signs of catness about. Although a doctor friend of mine assures me that it has no affect in humans except those already sick, and/or experiencing an immune system breakdown, scientists have found apparent connections with schizophrenia in humans.
