What purpose does the allusion to Peter Pan serve in this paragraph?

Anne Markerson never had to leave childhood behind. One of her responsibilities as the chief executive of Young Ones, Inc., is to play with the toys that the company manufactures. On weekends, Markerson enjoys the same activities she did as a child: biking, running, and walking in the woods. The quote “All children, except one, grow up” applies as much to Anne Markerson as it did to Peter Pan.
