On Wednesday Justine Henin announced she would be retiring from tennis. This surprised me for two reasons. The first reason I was surprised is because she is only 25 years old. The reason I was really shocked is because Justine Henin was ranked #1 by the WTA.She is going out on top.But wow. This was really unexpected.I don't know about you, but I'm floored. For her to retire is one thing. For her to retire right before the French Open, which she loves and which she's won four times is shocking...
