This is sort of on-topic, Abby, so please indulge me. I did some research at the local university after my B12 deficiency. I found unbelievable amounts of detailed "doctoring" a century ago. People like Addison, who truly looked at every angle of a disease and documented it. I agree with Alice. There is not as much looking and thinking now days. And putting pieces together. Dr. Andrew Weil said in a lecture I saw over a decade ago that pathophysiology is not even taught in medical school anymore. There's no time for it. How sad.

Sure seems like a lot of us here are - as Alice has said - zebras.
