What is so magical about childhood?

Childhood is magical because we live that phase of our life the way our entire lives should be lived.Our happiness is linked to doing things which feed our curiosity,enthusiasm or the fun of just doing it.We try to find the end of the rainbow,hold little red ladybugs in our hands,catch the fireflies in a glass jar,colour the walls or play silly rhyming games.Happiness is linked to the action without any agenda of desire or fulfillment in future.So we actually experience the joy and fun of living in the present because we link our happiness to the action in present and not the some payoff in the future.
We lived each moment and day as it came..Ever remember planning your every free moment when you were a kid.If you were playing football and a friend suggested swimming you were ready in an instant.There was no need to control the flow the events and one easily detached oneself  from whatever one was engaged in.There was flexibility and impulsiveness at the same time.Isn't that what we want to do--relish the fun of living our lives like we did in our childhood.
