Yaeh, childhood is the prime yaers of human existence. In this period we are so close to the Principle of Pure Attraction - the idea that dictates that everything in the universe fosters relations with everything else, without discrimination; much like matter in it's constant dance with the gravitational force. We had no prejudice, no fears, no hierarchies to be a slave of; only Pure Attraction and bliss, just like the more simple animals that don't have to be overly preoccupied with the lingering anxiety of te power game that humans have build around themselves as fences in this societal machine.
You can try to emulate this bliss all you want; there is no possibility that a NEET, although "carefree", could possible have the same innocence once present on childhood. We have been marked with the token of responsability, of social castration, of shame, and depression/anxiety. Not only our socioeconomical and physical conditions are at they prime in our childhood, but so is our mental functioning. Now we are too destroyed by this world - too "dead inside" - to even mimic the ways of the child.
