Narrator: This is Science Today. Playtime isn't just for kids - at least, for psychological reasons, it shouldn't be. In fact, psychiatrist Lenore Terr of the University of California, San Francisco, says when Sigmund Freud said a happy, balanced life depended entirely on work and love, he simply overlooked the importance of play.
Terr: Adults need to continue playing way past their childhoods. It is one of the three essentials of adult life.
Narrator: And Terr says playing doesn't necessarily mean just sports activities. There all sorts of ways to have playful fun - some may play chess, others may listen to music. But Terr cautions that play does not necessarily mean leisure.
Terr: Just because we keep trying to be couch potatoes, does not mean that at the time we are being couch potatoes that we are truly playing. Play requires super concentration - concentration that is better than the concentration that most of us have at ordinary times in our work or at ordinary times over lunch when we are talking to co-workers.
