Too busy to exercise? People who engage in regular planned physical activity say it increases both their capacity for work and their effectiveness. Among those who appear on the PBS special "Off Your Duff" which will be televised Tuesday, April 17, are (top) Senator Edward Kennedy, a jogger and tennis star Billie Jean King; (center) NBC "Today" show host Tom Brokaw, a jogger; and (bottom) pop singing star Livingston Taylor, left who play schoolyard basketball and Dick Smothers, a devotee of racquetball.
