I suppose we have all heard the story of the man who went to the GP because he was concerned about his father's failing health.
Patient - I am here about the old man - he is getting feeble and infirm, has trouble getting up in the morning, has to have a rest after any exertion, and as for his appetite - he has no interest at all. I took him out to the shops yesterday and the girl at the checkout was quite distressed at his appearance - he looks so old and wrinkled compared to just a few years ago. The barber says he feels guilty at taking his money, there is so little hair left to cut. What can I do about him, doctor?
Doctor - Don't worry about it, I see many similar cases, and no need to be embarrassed about discussing it with me. Just drop your trousers and lie on the couch and I'll take a look. We'll soon have your old man feeling perky again. . .
