I had a thought which made me laugh!
What if the reason people are for the moment unable to assign/attribute fixed and certain causes for aspergers/autism is that god is still thinking about it; hasn't decided yet what it is to be ?! !
All the things which we have not worked out yet, are loose ends which god hasn't got round to tieing up!!
He's still thinking about long distance space travel for instance. We'll hear about it when he's worked it out!

? ( maybe he'll get some ideas from the characters who have taken on a life of their own!! )

If God has our life in a book the mentality chapter would be 1256873 pages
