You wake up, turn off alarm, check the weather on your phone, turn on the TV & listen to the news or a show while getting ready to go to work. Maybe you skip that last part if you woke up late & have to rush, so you quickly get out of bed, wash up, dress, grab a quick bite to eat, & rush out the door.
If you drive to work you may actually get some sun in your eyes (season permitting). If you commute by bus/subway/light-rain etc. you're probably on your smartphone playing a game or texting etc. Then at work many if not most people are staring at a computer monitor for most of the day. During break & lunch you might be chatting with some coworkers, but likely at some point back on your phone texting etc.
After the commute you're at home & you sit down and turn on some combo of TV/Netflix/Playstation or fiddle on your computer/phone on social media/youtube (or this forum) for much of the evening between eating & pissing. Maybe a couple of nights a week you get out of your screen-zombie routine to the gym/sports or see a concert etc. Maybe you catch a movie (another screen). You go to bed reading a book on your phone/tablet, or *gasp* an actual paperback.
How familiar is most or all of this to you? How many hours a day do you typically stare at a screen? Despite being never being more connected technologically, recent studies show significant increase in social-isolation among teenagers, who are less likely to date, hang out with friends, have sex & see an increase in loneliness & decrease in sleep & teens getting their driver's license. Is our addiction to sedentary technology destroying our physical health & social lives? These graphs try to link it to the iPhone, but I think it can also be linked to smartphones & social media in general:
