prove socially healthier than television, since the Internet allows users to choose their information and to
communicate with others freely.
[4]The fact that Internet use reduces time available for family and friends may account for the drop in
well-being. Faceless, bodiless "virtual" communication may be less psychologically satisfying than actual
conversation, and the relationships formed through it may be shallower. Another possibility is that
exposure to the wider world via the Internet makes users less satisfied with their lives.
