Excerpt from this article:
It has become part of my daily routine to slip headphones on as I leave the front door. I don’t take them off until I reach my destination, unless I’m buying something in a shop or giving directions – as the writer Lucy Prebble has remarked, “taking off headphones is the new removing your hat”. I sometimes listen to music, but mainly I listen to talk.
Perhaps the biggest cost, though, is that I’m listening to myself less. When I’m riveted by the narrative of a real-life murder mystery, my thoughts don’t wander, and it’s only when thoughts are allowed to wander that they become interesting.
