I think Betty is only interested in psychology academically . She wants to learn about herself , probably her family . She wants to understand her issues and never got a clear answer . I can ' t see her happy as a psychologist or using that degree to help others . And I say this as someone who likes her character . However I think she would have been happy as a model and working in other roles in the fashion industry . She was clearly talented in organizing . She wrote well . She has flair . I could see her working in a fashion magazine . Wasn ' t Cosmopolitan starting toward the end of the series ? Somewhere that connects style with smarts . <| sep |> Pardon my ignorance and lack of research but what type of valve adjustment method is most common on Ducati motors i . e shim or bolt type adjustment for lack of a better known term . I know it can vary from motor type to motor type .
