There are two special areas, which aren't covered in the book. I'd particularly like to learn more from an expert in autism.
I am no expert, but i wonder if the exercises on body, smell and taste, or especially humming and the sense of taste, - could be a useful balance for autistic people and people who are especially sensitive or agoraphobic.
Again, i am no expert, but children and people with attention deficiency, might be helped by learning a balance of focussed and broadband sensing. Broadband games express something which is maybe otherwise, daydreaming.
I'd be very interested in communication with other people who could build on what i'm describing.
