Why are we so bored?

On average we spend six to seven hours in front of our phone, tablet, computer and TV screens every day. All this is simply becoming boring. Instead of performing varied activities that engage different neural systems (sport, knitting, painting, cooking, etc) to relieve our tedium, we fall back on the same screen-tapping schema for much of our day. The irony is that while our mobile devices should allow us to fill every moment, our means of obtaining that entertainment has become so repetitive and routine that it’s a source of boredom in itself. —UK Guardian
