Joe was an average skier, competing and winning numerous titles in junior and senior national ski events. As Joe says, " Skiing was it, everything, my world. " Joe’ s world collapsed on January 30th, 1955 when she skied off the outer round and landed helplessly on the slope. Her fourth, fifth and sixth cervical vertebrae (颈椎) were broken. For days, Joe hovered between life and death. By April it became clear that she would be paralyzed from the shoulders down. Joe underwent rehabilitation therapy with cheerful determination. She learned to write, to type and to feed herself. Once she had mastered daily living skills, she enrolled in a university in California at Los Angeles, where she studied art, German and English. After overcoming yet another personal tragedy, the death of her boyfriend in a plane crash, Joe graduated in 1961. By this time, Joe had chosen a new career goal, teaching elementary school children.
