— May 28, 2017
Excerpt from Business Insider -- "Alter said in his talk that screens 'rob us of stopping cues,' which are signals that remind us to move on. The distraction and entertainment is constant, unlike a newspaper which finishes when you reach the end. Instead, there is no obvious time to stop — so we don't."
