Watch out for those menacing subluxations, and you might live forever:
A subluxated vertebrae . . . is the cause of 95 percent of all diseases. . . . The other five percent is caused by displaced joints other than those of the vertebral column.- Daniel David Palmer, The Science, Art and Philosophy of Chiropractic. Portland, Oregon: Portland Printing House Company, 1910.
Causality should not be confused with correlation, nor coincidence.
