(CNN) This past week, former President Jimmy Carter and his wife, Rosalynn Carter, celebrated their 73rd wedding anniversary , making them the longest-married presidential couple in history (George H.W. But the secret to the Carters' success might be as simple as the fact that, well, they chose to stay together. Jimmy Carter embraces his wife Rosalynn after receiving the final news that he'd won the presidency in 1976. President Carter's 1980 reelection bid was unsuccessful, and studies do show that work stress can have a damaging effect on a marriage. Later, in 2012, the Carters chose to write a book together, a project that Mrs. Carter told CNN was "a terrible experience."
