answer: Sally Green, a swimming star, says she doesn't swim at all now because she's 20 and it's too old for a swimmer.
documents: #Person1#: Do you remember Sally Green, the swimming star? She was the girl who broke all the records at last Olympics. Where is she now? Last week our reporter Tom Parker went to see Sally in her home, California.
  #Person2#: Is it true that you don't swim at all now?
  #Person1#: I'm afraid so. I'm too old.
  #Person2#: But you are only 20.
  #Person1#: That's too old for a swimmer. If I swim in an international competition now, I wouldn't win. So I'd rather not swim at all.
  #Person2#: But don't you enjoy swimming?
  #Person1#: I used to when I was still small. But if you enter for big competitions, you have to work very hard. I used to get up at 6:00 AM to go to the pool. I had to train before school, after school, and at weekends. I swam 35 miles every week.
  #Person2#: But you were famous at 15. And look at all these cups.
  #Person1#: It's true that I have some wonderful memories. I enjoyed visiting other countries and the Olympics were very exciting, but I missed more important things. While other girls were growing up, I was swimming. What can I do?
