I would like to be able to tell what is AIDS, and what is aging. That would be really wonderful, if you could tell me which one was which. Doctors can’t tell ya. I had what the doctor called “Sudden Onset AIDS-related Arthritis.” Now, is that really what it was, or was that an age thing? I don’t know. I had leg problems, and I had bypass surgery. But was that due to the Kaletra, which is quite a possibility, or is it due to aging and genes?
