Medicaid is not Medicare; Medicaid is related to income, not work and age. I'm sure it is a surprise to many doctors to see someone young and be thinking "old" when they get a Medicare patient. It is still clumsy of a doctor to be so blunt, without knowing the patient to ask in such a fashion, risking being misunderstood as the eye doctor did, "What are you doing on Medicare since you are so young" implying there was something wrong with being on Medicare or disabled or young and not working, etc. I don't think the doctor meant it that way but he did not think before he opened his mouth; a problem I can relate to
