There is a device that you can attach to your refrigerator called the “Happiness Counter”.

 Basically, the device will scan your face to detect a smile. Smiling at the device will unlock the yummy yums in your fridge.

The Happiness Counter was developed at the the University of Tokyo. It was created because smiling contributes to mental well-being. It makes smiling a part of daily life especially to those who live alone.

The girl’s face is like,”Oh no you didn’t, Happiness Counter!”

 Why won’t this fridge budge?!
