An old friend of mine (likes to) tell (in some frequency) a specific tale of his youth. About his dad. About how his dad would scold them for being inside on a summer day. And about how they would respond.
"What are you doing?"
"If you're doing nothing, then do it outside."
The world beyond the back porch was, as we all know, a life-changing environment. Young legs became stronger. Young minds became sharper. And eventually, it replaced the indoors as a chosen destination almost entirely.
Unfortunately, times have changed. LINK
