Here is something interesting research I just now finished. It turns
out that there is a suspicious existence of distinct brain physiology,
developmental dyspraxia and general clumsiness in both autism and post-
traumatic stess disorder.

I can't imagine I'm the only one who has found this strange
synchronicity. All I can figure out is that politics is once again
intruding in science. I have a miserable suspicion that science will
NEVER find the cause of autism.
