When Fred and Lucille Bell met while singing in the church choir, the phrase "turn of the century" meant 1900 - only a few years in the past. Now the new century is within their grasp, as they celebrate their title as "America's longest-married couple." The duo from Swanton, Vt., will celebrate their 80th wedding anniversary in May. He was 20 and she was 19 when they were married in the Bell family home on May 24, 1916. They've lived on the same block ever since. Fred, now 99, isn't well physically, but the couple still lives at home, aided by round-the-clock caregivers. Lucille credits Fred with "never smoking, drinking or running around. He was a hard worker, and I was a stay-at-home mother. Of course, we've had our ups and downs, but we always ironed it out." The longest-married contest was sponsored by Worldwide Marriage Encounter, a nonprofit organization dedicated to enhancing the quality of marriage and family life.
