I wish I could afford a functional doctor and a nutritionist. I cannot, so I started educating myself. Plus I worked for many years with lots of medical doctors and scientists (at the Nobel prize level!). I had access to an extensive library, and I kept abreast of the latest research as I was a technical editor - I saw all the journal submissions before they went out! Then I worked for the Chief of Surgery at a local hospital - he was the editor of Archives of Surgery - so I was surrounded by all the surgeons at the hospital. I got over my fear of speaking to doctors a long, long time ago, AND I learned the terminology. I have time to do some research and it has saved my life so many times. The human body is fascinating!
