Here's another article in the realms of mental health and new media. Psych studies also suggest that you can become mentally addicted to fantasy football. It shares the common thread of other kinds of internet addiction where there is an "illusion of control." Or the player has to control the outcome. This is actually a blog entry I think from the New York Times website, so you can think of it as a blog within a blog.
*Again clinical psychology is still developing, so addiction diagnosis will not be perfect.
