Shawn Johnson's knee injury she sustained while skiing in 2010 has now put an end to both her career and hopes of competing in this years London Olympics. She said in a statement to the Associated Press, "It just little by little gets worse and worse. My body is to the point where I need time to rest and retire so I can be healthy for the rest of my life. It's hard to wrap my mind around. Gymnastics has been my entire life, and now it's no more."
