Are we all a bit crazier than we used to be? If so, why? Will the world keep getting crazier and crazier? Or will we, as a society, find our way back to a healthy collective state of mind? Or will things get worse? And what exactly is sanity anyway? What about the role of social media in all of this? And, if you get fed up of chatting about such unhappy stuff, stick around for the personality tests etc, that supposedly really work!
