Movement is the essence and meaning of our life. We feel so much more alive when we are in motion, while people who spend hours motionless tend to have trouble connecting with the outside world. Whether you dive from a high cliff, play your favorite sport, dance at a rave party, or simply walk down a path with autumn leaves rustling under your feet with the love of your life by your side, all those things make your life richer, more beautiful, and more fulfilling. This set of pictures beautifully captures the joy of never-ending motion that enriches our life. (Photo by Brian Snyder/Reuters)
