Need a pick-me-up? This Zumba video is just the thing to put a pep in your step. Created to celebrate the United Nations' International Day of Happiness [1] (today!), the video is set to an infectiously peppy track — "My Jam" by dancehall artist Mr. Vegas and Pitbull — and features 8-year-old dancing sensation Aidan Prince Xiong [2]. Watch the smile-inducing video, and try not to dance along as you celebrate the first day of Spring.
