Because most of my career in the classroom has been at art schools (beginning at Bennington in the 1970s) I am hyper-aware of the often grotesque disconnect between commentary on the arts and the actual practice or production of the arts.
I don't practice but I am still officially in paediatrics. I keep in touch with journals and I have a very good data bank of medical information and there is a key thing for a writer knowing where to go. I know where to go to get the information that I need.
