I, too, read articles from Cleveland Clinic because I trust them. Thank you for clarifying the preceding post regarding the magazine. I also trust the Mayo Clinic. Most of the "doctoring" I do on myself are from these two clinics. Where I live we have Loma Linda Clinic. They are rated highly but I find it not to be true. I have been through many primary care doctors. Either they leave or I leave. They do have excellent specialists though. I had to have a full hip replacement and I wanted a particular surgeon because I heard he was the best. I had to wait several months but he was the best. Now I walk without pain and only a very small scar which you can scarcely see.
