Very surprising answer, but demonstrates a few things:
1. conservatism of the medical profession
2. conservatism which is understandable in a profession charged with responsibility for so many human lives
3. conservatism which is understandable in a profession with such high malpractice insurance expenses (Saw a story somewhere about a medico who entered medical practice in the first half of the 20th century. Initially, he was paying $70 per year for malpractice insurance. By the time he retired, this had climbed to $70,000 per year!)
4. if you have a new medical idea, be prepared for a long, hard slog to get it accepted — witness the discoverers of glycemic index & the value of insulin for treating diabetes
5. everything is obvious once you know the answer
