nkonor and ctsooner, I recently retired from a career as a medical scientist (in the field of virology). Your testimonies reminded me that at about the time I was in med school, nearly 50 years ago, the concept of "autoimmune" disease was described, and there was great optimism that diseases like MS, Lupus, Rheumatoid Arthritis, etc, would soon be understood and made cureable, as opposed to "treatable". I am very sad that this endpoint has not yet been reached, even after so many years have passed and even as a result of a massive increase in our understanding of the immune system. My heart goes out to both of you guys, and your posts should make the rest of us who are in good health realize that we are very lucky and that our arguments about audio gear are really quite trivial, even silly, by comparison to what is really important in life. Carry on.
