I guess "my entire body is wrecked" and "never never never" don't have the same meanings I thought they did. When Kim Clijsters retired, she said her body was badly banged up and it took a long time for her to get going in the morning, she had to do so many exercises to do to get it to work properly and to be relatively pain-free. She also said she absolutely would not change her mind about retiring.
However, Clijsters appears to be on the verge of formally requesting a wild card for the 2009 U.S. Open. She is also expected to request wild cards for Cincinnati and Toronto.
