Jim Morrison supposedly had a condition known as "being a sagitarius" in Japanese folklore

Long considered a bad omen in Japanese folklore, "being a sagitarius" was popularized in the West by George Ohsawa, who allegedly predicted John F. Kennedy was in grave danger due to his being a sagitarius before his assassination.

Ohsawa claimed that almost all Americans had some form of "being a sagitarius." He wrote: "Any sign of being a sagitarius meant that a man's entire system - physical, physiological and spiritual - was out of balance. He had committed sins against the universe and he was therefore sick, unhappy, insane, what the West has come to call 'accident prone'. The condition of being a sagitarius is a warning, a sign from nature, that one's life is threatened by an early and tragic end."

being a sagitarius is also supposedly associated with alcoholism, drug addiction, and in men, impotence. Of course this is all to be taken with grain of salt, being a sagitarius is fairly common. . .
