This is the age of the "superfad". Products, ideas and habits that surge into our collective conscience - and frequently burn out just as fast. In this new podcast from Stuff, two of our millennial reporters dive into the crazes. Laura Walters and Katie Kenny have spent a week in a waist trainer, crammed into a tiny house and vegged out on the couch for hours of binge watching to deliver Superfad. Each episode combines lively insights and revealing personal stories from well-known New Zealanders. We also explore the important social and cultural questions raised by the rapid rise and fall of 21st century fads.
