ABSTRACT
A 66-year-old retired sheep farmer presents with a persistent cough, dating from a cold some nine months ago. He has become more short of breath on exercise, and he wheezes occasionally, although he dismisses these symptoms as being due to his increasing weight following retirement. On examination, he is short, stocky and overweight. His breathing is somewhat noisy but his chest is clear on auscultation. Neurological examination is normal. There is no fatigability.
