At the VA with my hubby. So many older men and women of shuffling steps using canes or in wheelchairs.
Hard to recall that they were once young and fit, rucking 70 lb. packs, driving large wheeled or tracked vehicles, listening for sonar pings, landing planes on ships, or jumping out of planes and helicopters.
Time marches on. The old soldiers, sailors, airmen, and Marines move a little slower now.
