Doctor John and Doctor Guy wade into a swampy mosquito infested marsh to discuss plasmodium falciparum and malaria in all its historical glory.  Damn you mosquitos, you could have spread something good, like "the word" or even "Christmas Cheer" but all you've done is given us the gift of Malaria!   With that said, any disease that led to the creation of the Gin and Tonic can't be all that bad... unless you get it.  then it is all that bad.
