How many adults get sucked into the wormhole of technology (TV/computer)

[iLovePhysics]

addiction & can't control themselves? I just wondering if I should persuade my classmates (who are college students/adults) about how to inform them of the problem of technology addiction and how it hurts our society in a negative way (obesity, poor vision/social skills, negative influences mentally and physically).

What do you think I should talk to them mainly about to grab their attention and agreement on this issue? I'm focusing mainly on TV and computer uses of my speech because I can relate it to myself. Thanks.
