Narrator: This is Science Today. There have been recent media reports that across the nation, some adults are returning to the games of their youth, including kick-ball and dodge-ball. While some may laugh at the thought, this type of adult play is what University of California, San Francisco psychiatrist Lenore Terr calls one of the essentials of life.
Terr: Freud had been asked many, many years ago what made a normal adult and Freud said, "the ability to love and work." Now that was 19th Century Vienna talking and in the 21st Century America, we have to say to love, to work and to play.
Narrator: But Terr says that doesn't just mean sports. Play can be defined as anything done just for the fun of it and can give people fulfillment, make them more flexible and Terr says can even save some marriages.
Terr: I think that a lot of marriages fall apart because the play aspect of the marriage isn't good enough. It is difficult because men and women play differently and that they traditionally have different ways of playing. I think that in long-term relationships, they have to compromise and find some ways of play that they both enjoy.
