That does mean that she was 29 when the show started and 38 when it ended. That girl had the genes. Died from pancreatic cancer...which is one of the least survivable. I think you can consider 83 years a full life. After that age, I'm sure quality starts going down hill for most. I would put her in the catagory of the other 2 women who had great tv shows during that time frame...I dream of jeannie and bewitched. probably too old for most posters on here to remember. All 3 women were hot hot.
Some of the most beautiful women ever on television are from that period. Elizabeth Montgomery, Barbara Eden, and Donna Douglass. Joan Collins, who was on the Harlan Ellison episode of Star Trek, is another.
