I am an adult who was quite precocious as a child. I can relate some of my symptoms over the last few years to autistic like symptoms, or mercury (and flouride) poisoning. Brilliant, but forgetful, distracted. Wrapped up in my own thoughts. Caring, but distant. Don't like schedule, but do better with one. Felt bound, in my own world, and if capable of leaving it, didn't feel the need or desire to. Lots of walking through life in a trance.
