The symptoms – you can rank your own children or spouse on this list, if you haven\’t got enough to argue about – are all recognisable from other addictions: how does your internet use affect the rest of your life and mind? How much do you crave it? Do you deny it or lie about it? And yet the thing itself – these games that set the social mind and the competitive spirit alight simultaneously – are unlike anything you would know about the world of toxins.
