Clijsters: Olympics like school field trip

Kim Clijsters, who will retire after the U.S. Open, says that competing in the Olympics makes her feel like a kid again. "You kind of feel like you are going on a school trip, when we took the train and we were all dressed the same and had our backpacks," the four-time Grand Slam champion told reporters. "It was fun and it was exciting, having been on tour for 15 years, to have a new experience. I look forward to just getting to feel what the Olympic atmosphere is like. I am not really thinking about retirement until I have come to that. I am still here because I want to do well and I want to play good tennis."
