Yes, it could be. One thing they knew that we seem to have lost is the ability to play and work together. Western culture seldoms sings together outside of certain limited venues such as church, for example. Music comes from a radio or a CD, not from the heart.

Play is structured and usually watched instead of participated in. Go fly a kite, just for the hell of flying a kite, in a public park. Dig a hole in your back yard, just for the hell of it. See what sorts of looks you get. And yet, as a child, you may have done both of these things.

Roll down a hill. Twirl around until you're dizzy.

Listen to what the neighbors say about you.
