Wendy went to the doctor for a tick bite, and the doctor gave her some pills.  I went to a different doctor for the same exact thing two days later, and I was told to get a blood test.  When I asked my doctor why there were two different diagnoses for the same ailment, he said, "Practicing medicine is an art."  Now I ain't no medical doctor, but I can't think of something that should be approached more scientifically than the human body and the treatment of its various diseases.  I kind of get the fact that different doctors might disagree on treatment options, but as I said many moons ago, I look forward to the day when doctors are replaced by the following code:  
if (patient.sickness = "tick bite") {
   prescribe_pills();
}
Update:  Health insurer WellPoint will be using IBM's Watson to suggest treatment options.  Boom. #health
