U.S. Air Force Airman 1st Class Peter Zuniga, 86th Logistics Readiness Squadron aerial delivery specialist, dances during a photo shoot on Ramstein Air Base, Germany, Sept. 14, 2017. Zuniga believes that being happy is important to overall health. “Healthy aging to me means being healthy in all aspects of your life, not just physically. Being happy is being completely yourself, and I believe the happiest people live the longest lives.” (U.S. Air Force photo by Airman 1st Class Savannah L. Waters)
