"Teenagers who spend a lot of time watching TV or playing video games are at higher risk of developing depression as young adults, a study has found.
American researchers looked at the viewing habits of 4142 healthy adolescents and followed them up seven years later, by which time 308 had developed depression.
When the study began in 1995, DVDs and the internet were not widely available and the teenagers used different electronic media for about 5.7 hours a day on average."
A) Video Cassettes? really?
B) in the past 13 years 'Electronic Media' has changed in massive ways, DVD's being somewhere in the middle of the big changes a long with a massive shift of the focus of gaming from singleplayer games to multiplayer games.
C) 20 percent of all teens develop depression in the US alone with wide ranging causes and in seven years that this study took 308 out of 4142 teens developing depression doesn't suprise me.
