Toxoplasmosis

My cat does not have toxoplasmosis. WTF? I thought the worldwide infection rate was around 50%. The actual rate is, from Wikipedia, "It is estimated that between 30% and 65% of all people worldwide are infected with toxoplasmosis."

The behavioral aspects are fascinating - check out http://en.wikipedia.org/wiki/Toxoplasmosis from more great info. The schizophrenia part is most delightful.
