He is an office worker who has a mostly sedentary lifestyle; however, he has noticed that recently he feels tired and short of breath when going on long walks with his wife. He also has had a hacking cough that seems to linger, though he attributes this to an upper respiratory tract infection he had 2 months ago. He has diabetes that is well-controlled on metformin and has smoked 1 pack per day for 20 years.
