The first, termed the "reflux theory," proposes that respiratory symptoms are the result of micro-aspiration of gastric contents into the lungs and/or bronchia
. The second, called the "reflex theory," proposes that constriction or collapse of bronchial tubes is a vagus nerve-mediated event that follows acidification of the lower esophagus (Garrigues and others 2003).

In Bow Down (1971), an extraordinary dramatic piece based on various incarnations of a ballad, "The Two Sisters" he dramatizes the lyric's fraternal murder by mingling Middle English and Scandinavian versions with the plain, even base, language of modern life.
