Transplant of a smokers lung

You have to imagine this. A young woman (28) from Great Britain suffers of cystic fibrosis and has two new lungs transplanted. So far so good. 

But a good five months after the operation, the woman dies of what is called pneumonia. The woman had had two lung transplants from a donor who had smoked for 30 years.  

Apart from the fact that the health authorities make excuses and point out that organ recipients can't expect brand new organs, this may have been a medical test of how long such a well-smoked lung might last. Terrible like that.
