So you've jumped off from David Bowie's SciFi film, The Man Who Fell to Earth, with your own title? That suggests a certain ambivalence and, possibly, a sense that your son's progress is in the hand of the gods. As yet there are no known diseases, only names, for psychological/emotional tendencies (a guess) such as Asberger's and Autism, although the drug companies would probably love to nail a name so they can prescribe drugs at great cost to mask the real symptoms. Just where do you stand with this? What are your hopes for your son? Sympathetic and very interested.
