So read the subtitle of a story in today's Palo Alto Weekly. Stanford's Virtual Human Interaction Lab researchers have been studying how people change their real-world behavior by watching virtual representations of themselves (known as avatars). The researchers have found evidence that what one's avatar does in a virtual-reality game or world (like Second Life) can have real health implications in everyday life. For example, watching your virtual self get fat on-screen will help you decide to skip the chocolate bar at snack time.
