Dave Lindley is a pretty virulent non-smoker. Hey, quit smoking and you might be able to sing just like Mr Dave!!! On second thought, that might not actually be such a great incentive ...
Last year I went to Phoenix for a week with the family; we played tourist. One day we went to their science museum, and they had this Bodies in Motion exhibit... they take actual people whose bodies were donated to science, and embalm them using some sort of polymer. You could see the various systems / musculature / nerve systems, etc. in the different models displayed. Fascinating, as Spock would say. Of course they had slices of various diseased organs, cross-section slices of obese people, and good lung vs. smoker lung (ewwww; not pretty!). At the end of the exhibit was a clear box for tossing away your ciggies; the thing was pretty darn full.
I've traveled around some big towns in the US and it's evident that there are several traveling exhibits like this. Look for an unskinned body on the billboard in a large metro area with a science museum; that's the exhibit; it goes by several names.
Best of luck, Freddie. Tobacco really is a good thing to quit.
