Consider this: Patient: "I am sick." Physician responses: 3500 years ago - "Here eat this root" 2500 year ago - "That root is heathen - say this prayer" 150 years ago - "That is superstition - drink this potion" 50 years ago - "That potion is snake oil - take this pill" 15 years ago - "That pill is no good, take this antibiotic" Today - "that is not natures way - here eat this root"
