Successful Aging: What is a geriatrician, and do I need to see one?

Q. I am 79 years old and recently widowed. Since my regular primary care physician moved, I had to find a new one. Given my age, I decided to see a geriatrician. My initial visit was professional and thorough; the doctor was cordial, attentive and quite nice. Yet I just did not feel he was right for me. Note: I am healthy, walk several miles a day, volunteer at a hospital, care for my two grandchildren one week per month and have a very full life. Should I have seen a geriatrician? M.L.
