Robinson once told future Hall of Fame inductee Hank Aaron that "the game of baseball is great, but the greatest thing is what you do after your career is over." Robinson retired from baseball at age 37 on January 5, 1957. Later that year, after he complained of numerous physical ailments, he was diagnosed with diabetes, a disease that also afflicted his brothers. Although Robinson adopted an insulin injection regimen, the state of medicine at the time could not prevent the continued deterioration of Robinson's physical condition from the disease.
