Coolconchita, please do not take my jabs at Conchita personally. I'm just poking fun. I have never been a fan of Conchita, but that doesn't mean she has no talent. Conchita has had an excellent career. I just look at players like Conchita, ASV and Michael Chang (and Michael Jordan for that fact) and shake my head. While I can appreciate their love for the sport and their accomplishments, I also think a player should know when to walk away from the sport, before the sport walks away from them. Conchita has nothing left to prove, but she should also know when to walk away (a la Graf, Courier, Novotna, etc.). And before the whole Conchita-brigade starts in with "Don't tell Conchita when to retire...yad, yad, yad... I'm sure Conchita knows her game is not where is use to be and the players are just getting younger, faster and stronger and the likelyhood of her making it back into the top 20 or top 10 or top 5 is between... well you get my point.
So to answer your question, in a word, nothing.
