I wouldn't say that your childhood is perished? Yes much of the conscious memories have disappeared but your subconscious is a formation and continuously evolving energy that has been developing from the day your were born. The current you in a result of every stimulus you ever received whether you remember it or not. You are still a manifestation of all of the memories you have forgotten, ever decision you make from this day forth will be influenced by every experience you have had.
