“Gray notes that the tendency of kids to introduce danger and risk into outdoor free play, such as when they climb walls and trees, or skateboard down staircases and railings: They seem to be dosing themselves with moderate degrees of fear, as if deliberately learning how to deal with both the physical and emotional challenges of the moderately dangerous conditions they generate... All such activities are fun to the degree that they are moderately frightening. If too little fear is induced, the activity is boring; if too much is induced, it becomes no longer play but terror. Nobody but the child himself or herself knows the right dose. Unfortunately, outdoor physical play is the kind that has declined the most in the lives of American children.” — Greg Lukianoff & Jonathan Haidt
