A SHORT HISTORY OF MEDICINE:
"Doctor, I have an ear ache."
2000 BC: "Here, eat this root."
1000 BC: "That root is heathen, say this prayer."
1850 AD: "That prayer is superstition, drink this potion."
1940 AD: "That potion is snake oil, swallow this pill."
1985 AD: "That pill is ineffective, take this antibiotic."
2011 AD: "That antibiotic is artificial. Here, eat this root!"
Moral: Inevitably, all effective change processes come around full circle.
