"Some poor guy discovered that most ulcers are caused by a bacteria. Proved it, was screaming it from the rooftops, and was completely ignored."
Great point!!!!
The same was true of scurvvy two hundred years ago. It was thought scurvvy was an std (sailors mainly got it and we all know about sailors). A doctor proved it was the lack of Vit C but was laughed at.
The scurvvy/std myth lasted until as late as 1920 (there are medical magazine articles arguing the issue from that date).
Myth have a life of their own.
