Manure reduces development of lung cancer

Scientists have discovered that working with manure drastically reduces the risk of developing lung cancer.

Dairy farmers are five times less likely than the general populace to develop the disease, New Scientist magazine reports.

The study found farmers typically breathed in dust that consisted largely of dried manure, and all the bacteria that grew in it.

New Scientist said adults who had a greater exposure to germs than usual might build up a better resistance to bugs, including cancer.

What about politicians? They should never need to worry about lung cancer.
