When babies and little kids feel joy, they move. They can’t help it! This evolves into dancing, and if we didn’t become so self-conscious as adults, we’d all be dancing to show happiness. That’s why we feel so great watching kids dance: because they radiate the joy of movement. Robert Jones edited this series of clips, some you’ve seen before, into a supercut set to Taylor Swift’s song “Shake It Off.” -Thanks, Robert!
