What does Jonas laughingly suggest should be studied by a committee?

In "The Giver" by Lois Lowry, Jonas jokingly suggests that the committee should study the concept of "stirrings," which refers to the feelings of attraction and desire that adolescents begin to experience. He finds humor in the idea of a formal study on something so natural and human. This reflects the controlled and regulated nature of his society, where even emotions are scrutinized and suppressed.
