Benjamin Franklin nailed it when he said, "Fatigue is the best pillow." True story, Benny. There's nothing like pushing your body so far past exhaustion that you'd willingly, even longingly, take a nap on a concrete slab.
When I came home from war, it was time outside that kept me alive, and ultimately connected me to a community of veterans and non-veterans who helped me later to thrive. I realized it was the country --- the very physical country contained in all its forests, mountains, beaches, tundra, prairie, and everything in between --- that I fought for. It was these lands and trees and waters that allowed me to meet my fellow resident as an equal; we had the same opportunities, we had the same access. Even if we didn’t have all of our limbs, or all of our mind still with us, we could make what we chose to make of a day outside.
