An old man with a deteriorating memory went to have an assessment one day to determine whether his memory had deteriorated to the point where it would be preferable to have him admitted to a nursing home.  The Consultant who was carrying out the assessment and making the recommendations with regards to the next step in the patient's care pathway said to the old man "Somebody has filled a bathtub full of water.  Next to the bathtub is a spoon, a teacup and a saucepan.  What would be the quickest way to empty the bathtub?"

The old man looked at the Consultant and replied "Why, the saucepan, of course.  The spoon is way too small for the job, a teacup would take ages to use, so therefore it would be quicker to empty the bathtub using the saucepan."

And with that the Consultant said, "Well, actually, the fastest way to empty the bathtub would be to just pull the plug instead.  Now, would you prefer to be housed in a mixed nursing home or a male only nursing home?"
