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)

Number 10. BELL H-13 SIOUX was a two-bladed, single engine, light helicopter built by Bell Helicopter. Westland Aircraft manufactured the Sioux under license for the British military as the Sioux AH.1 and HT. In 1947, the United States Air Force ordered the improved Bell Model 47A. Most were designated YR-13 and three winterized versions were designated YR-13A. The United States Army first ordered Bell 47s in 1948 under the designation H-13. These would later receive the name Sioux. The Bell-built H-13 B is seen airborne in this April 29, 1951 photo. The helicopter is equipped with a 173 horsepower engine, cruises at 85 miles per hour, climbs 900 feet in a minute and has a service ceiling of 11,500 feet. (Photo by AP Photo)
