Stafford Cohen, M.D, retired cardiologist from a Harvard-teaching hospital talks about his experiences there and how and why  medicine has changed. This much-loved and noted physician also tells us what it was like to retire after 48 years  from a busy practice and then to  turn to writing three books, the last being his medical murder mystery, We Live And Die By Electricity.  And now Dr. Cohen is thinking about a fourth book!Only great vibes from Stafford!
