Smoking Room Ceiling

Gets the point across!
One of my best mates had a near fatal heart attack Friday.
He was a smoker till then.
As were most of the guys in the Cardiac Care Unit.
The nurse looked at an image of his heart and said he had been smoking for over 40 years – which was true. Apparently smoking causes a change in the shape of the heart and this young girl had seen enough to know pretty well by the shape of the heart how long a person had been inhaling cigarette smoke.
