There have been suggestions of autism and schizophrenia in relation to cave artists for some years now and of course Jayne's "Bilateral mind" has been popular for a couple of decades at least . It seems to me most blokes have a large chunks of autisism in their behaviour , girls don't seem to suffer from it to the same extent . The exceptional , in both senses ,ms Grandin's "Animals in translation " is a treat with many insights into animal behaviour and I think is jist oot in paperback.
