A smile costs you nothing, and yet offers adequate exercise for your facial muscles while bringing down the guard of others around you. Well, you can add one more benefit to the list – it will make life easier for folks who spend plenty of time opening a fridge to snack on its contents. Scientists at the University of Tokyo Sony CSL (Computer Science Labs) have made such a scenario possible, hoping to force those who are feeling down to cheer up by requiring them to smile so that they can easily open the fridge's door.
