ROSEBURG, Ore. — Pauline Phillips leads a busy life. She still drives, does water aerobics every morning at the YMCA, leads Rosary at the Catholic Church and serves dinner at the Elks lodge, defying the fact that she is 98 years old. She was born on April 21, 1920 and has outlived two husbands. On May 14, Phillips had a pacemaker implanted after experiencing blackouts and ending up in the hospital.
