Argentine Tango... is it really for everybody?

Someone once asked me why Argentine tango attracts people so much? They seem to have a strange addiction, they seem happier and more extroverted, they change the way they walk and present themselves to society, they improve their wardrobe and even their way of speaking is different, they listen to tango music all the time and they don't get tired, they go to Tango marathons, Milongas and they even greet with a hug. Why they make all this changes in their life?
