I'd say, time for a visit to the doctor. As Steve mentioned, heart and related issues pop to my mind for an 82 year-old with shortness of breath. I wouldn't suggest doing anything until a doc (possible even a cardiologist) has checked him over.
It may just be the new normal for him at 82.
I'll be in the shop.
