is it true that serena withdrew from the olympics because she was scared for her safety of a possible terrorist attack or is this just a rumour ? 1. she took 8 months off for knee surgery and her knee still isnt better yet after topnotch surgery and physical therapy on a world class athlete ?? if her knee is really hurting and it may be why is it taking so long to heal this isnt normal is it ? 2. she seemed fine in the events this summer leading up except for the occasional pullout of matches with formidable opponents. 3. she made comments earlier this year that if she felt her safety may be threatened in any way at the olympics she wouldnt go. 4. if it was really a injury why isnt she still going to athens to support the team , but just not playing, is that allowed ? mabye venus will pull out next when she tries to tie her shoelaces again over there, who knows ??
