In the past few years, the fortunate among us have recognised the hazards of living with an overabundance of food (obesity, diabetes) and have started to change our diets. But most of us do not yet understand that Facebook is to the mind what sugar is to the body. Facebook feed is easy to digest. It has made it easy to consume small bites of trivial matter, tidbits that don’t really concern our lives and don’t require thinking. That’s why we experience almost no saturation. Unlike reading books and long magazine articles (which require thinking), we can swallow limitless quantities of photos and status updates, which are bright-coloured candies for the mind. Sadly, we are still far away from beginning to recognise how toxic Facebook can be.
