I wonder if the purest state is the state of the child.
My trade is on nursing. A few days ago I cared for a 30 something patient who had suffered a TBI a few years ago. She was admitted to the hospital for “agitation” not the greatest admitting diagnosis, but anyway.
The point is the patient is violent, throws punches, etc.
I don’t want to say I treated the patient as a 5y.o., but I approached as I would approach a child. In a non threatening manner. Sorry, I’m going off topic.
The point is that the patient was very playful, like a child. The brain of this person was not able to do math or read, but it’s spirit remained. And it was very much playful the way a child would be like.
