Former U.S. President Gerald Ford and his wife, Betty. Mr. Ford lived to 93, older than any other president.
Four American presidents lived past ninety. John Adams, Herbert Hoover, and Ronald Reagan each lived ninety or more years. But Gerald Ford lived longer than any other president. He was ninety-three and a half when he died in two thousand six.
SHIRLEY GRIFFITH: Professor Olshansky says gray hair, hair loss and other changes are part of aging and may result from something in our genes. So presidents are no different from the rest of us. But the researcher thinks there are three reasons they outlive other people. Most presidents are well-educated. Many are wealthy when compared to other Americans. And they have the best medical care possible. They know how to stay healthy, and have the best doctors. As a result, they can afford to live a healthy life long after they leave the White House.
Professor Olshansky says, "It is a classic illustration of the benefits of socioeconomic status." His study was published last month in the Journal of the American Medical Association.
