Selecting medical topics of interest to the family audience, Dr. Rutstein discusses modern medicine in a conversational format with Parker Wheatley, general manager of WGBH-TV, Boston. The original 40-week series, from which these episodes were selected for national distribution, originated over WGBH-TV through a grant-in-aid to Harvard University and the Lowell Institute from the John Hancock Mutual Life Insurance Company of Boston.
