BRAIN DRAIN?: Recent research says being overly dependant on smartphones makes for an underactive brain.
Having the world at our fingertips diminishes the role of our brains in daily life, according to researchers in Canada.
"Decades of research has revealed that humans are eager to avoid expending effort when problem-solving, and it seems likely that people will increasingly use their smartphones as an extended mind," says lead author Nathaniel Barr, a postdoctoral researcher at Waterloo.
