A rat being trained by the Cambodian Mine Action Centre (CMAC) is pictured on an inactive landmine field in Siem Reap province July 9, 2015. Gambian pouched rats were deployed to Cambodia from Tanzania in April by a Belgian non-profit organization, APOPO, to help clear mines. They've been trained since they were 4 weeks old. Cambodia is still littered with landmines after emerging from decades of civil war, including the 1970s Khmer Rough “Killing Fields” genocide, leaving it with one of the world's highest disability rates. APOPO has used the rodents for mine-clearing projects in several countries, including Angola, Mozambique, Thailand, Laos, and Vietnam. (Photo by Samrang Pring/Reuters)

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)
