If you put humans in a sterile bubble you get a different set of diseases, to a considerably greater degree because your immune system evolved in an environment where you actually got infections.

Are there any benefits to toxoplasmosis besides some people finding the vector cute? The alternative isn't living in a sterile bubble.
