Semiretired physician of 41 years. Previous occupations - USAF pilot, undergraduate training in chemistry and math. Longtime Interest in history of western tradition. No formal education in economics, no investment advisor or manager. Primary interest is personal finance investing with emphasis on analysis of closed end funds, especially their performance metrics and particular use of leverage, optionwriting and ROC.
