German automaker Volkswagen financed a study on the connection between creativity and health whose results are at least thought-provoking.

The research is called “The Fun Theory” and it is set out to prove that people’s behavior could be changed by making menial tasks enjoyable in some way.

As part of the initiative, the company installed musical steps on the staircase of a subway station in Stockholm, and observed if more people would take the healthier (and more fun) option rather than the escalator. 

The study found that 66% more people used the stairs than usual on that day, which is a testament to the playfulness and inner child that’s found within all of us. It showed that efforts to make cities more fun can actually make us all happier, fitter and healthier.
