About a year ago my son and I were leaving a swim meet and I asked him what took so long to cool down/how much was his cool down? He admitted that he lost track of how much he was doing and just kept swimming because he was figuring out the plot of his novel while he cooled down. And then for the half hour ride home did the audio version of the novel's early draft.
