Chiropractic is based on the theory that if the spinal column is properly aligned, nerve impulses can freely flow along the spinal cord. If the spinal column is out of alignment (a subluxation) the flow of nerve impulses is interrupted and disease (not just back pain) result. This is called the subluxation theory.
Gerald Rudolph Ford, Jr was the thirty-eighth President (1974-1977). He was the only President who was never elected as either Vice President or President. He became President after the resignation of Richard Nixon over the Watergate scandal. He was born Leslie Lynch King Jr on July 14, 1913, in Omaha, Nebraska. His mother married Gerald Ford, who adopted the boy and gave him his name.
However, Ford is the only one who was never elected to the Executive Office (as either President or Vice-President). Eight Presidents took office without being elected to the presidency, having been elected as Vice Presidents and then promoted from that position.
