Kids, happiness and your brain

I watched a remarkable video a few years ago on Ted about Jill Bolte Taylor having a stroke. She's a neuroanatomist and studies the brain so it was an interesting time for her. In her talk she explained that the left side of her brain had a stroke and after intense pain she would then see that her body would blend with the environment around her and that everything was connected in some way. Then her left brain would kick in again and she's be herself, 'trapped' in her own body.
So now to some things that I thought of about children. They seem not to realise that they're separate individuals and that perhaps their right brain is evolving faster so that they too feel connected with everything. Especially parents :-D. Two other situations I've seen that seem to back up this theory of mine (maybe someone else has though of this too. Who knows). When kids colour in a drawing, they don't care about the boundaries of the picture. The lines that separate the individual items in the picture are not important. The other situation is that kids can be ecstatically happy for no reason or the simplest of reasons. Perhaps in our development of the right half of the brain, we lose the fun, the romance, the spirituality at being one with the universe.
