Who should have the pinkest lungs a city-dweller smoker or farmhand?

Neither city-dweller smokers nor farmhands would typically have pink lungs.

Smokers' lungs are often discolored due to tar and other chemicals inhaled from cigarettes. Farmhands might have lungs discolored due to dust, dirt, and other particulates inhaled while working. Healthy lungs are typically pinkish-white.
