From Yahoo News:
Researchers at the University of Maryland who asked 200 students to give up all media for one full day found that after 24 hours many showed signs of withdrawal, craving and anxiety along with an inability to function well without their media and social links.
Susan Moeller, the study's project director and a journalism professor at the university, said many students wrote about how they hated losing their media connections, which some equated to going without friends and family.
"I clearly am addicted and the dependency is sickening," said one student. "Between having a Blackberry, a laptop, a television, and an iPod, people have become unable to shed their media skin."
Moeller said students complained most about their need to use text messages, instant messages, e-mail and Facebook.
"Texting and IM-ing my friends gives me a constant feeling of comfort," wrote one of the students, who blogged about their reactions. "When I did not have those two luxuries, I felt quite alone and secluded from my life."
Thank God that I — an educated, thoughtful, mature person — need never worry about such addictions.
But seriously: there is a tradition of human reflection in which being in the midst of busyness is to be "secluded from your life," and to be alone is to find that life. Just in case we've forgotten.
