A number of years ago (10-12?), my brother was mistakenly diagnosed as schizophrenic. As a result, my mother and I were doing as much reading as we could. We weren't computerized in those days, so we were reading books. Perhaps this was a theory in vogue for awhile.
I haven't kept up on the latest, so I'll guess this is NOT valid. I'm sorry for any confusion.
Glad to hear it was mistaken though.
