Today is smile power day! Time to exercise your Zygomaticus major muscle and 25 other muscles that activate when you smile. You also use more calories smiling then frowning. It’s also an important way to communicate to one another and we hope that today’s music brings a smile to your faces. Feel free to share a pic of your smiling faces in the comments below! #circusworld #baraboounited #smilepowerday #bighistoryishappening | Circus World
