We spend a lot of time looking at screens. According to the New York Times "adults are exposed to screens – TVs, cellphones, even G.P.S. devices – for about 8.5 hours on any given day."
I actually think that might be low. I'm in e-marketing, and that means the bulk of my work day is spent looking at a computer screen. At home, I enjoy surfing the web, reading my RSS feeds, tweeting and maintaining this site. That's another couple of hours, easy. Then, there's TV time. I'm guessing that's another two hours, sometimes more. Heck, a hockey game is a three hour block... and I'm addicted to The Wire on DVD.
Yeah, I'd say 8.5 hours is low for me. On weekdays, anyway.
On average, how many hours a day do you spend staring at a computer screen, TV, or cellphone?
