Porcupine_I said: guess which one is your lung |
Just on a side note about this ...
I once talked to a pathologist and he was complaining about CSI myths and other misconceptions people had about his job and he said that one of his biggest annoyances was this exact type of propaganda from anti-smoking groups. His point is that if you live in a major city the amount of smoke and grime in everyone's lungs makes it impossible to determine who is a smoker based on outward appearance of the lungs.
Basically, most of these anti-smoking groups are taking two extreme cases (a two pack a day smoker who works on a loading dock around diesel trucks and someone who lives in an extremely remote rural area) and is using them to scare people.
