I saw a man (about 75 years old) standing outside an exhibit building at an antiques market in Lake Co. Ill, 15 degrees, sleeting, snowing, and he was dragging an oxygen tank around but had the tube out of his nose (it had a huge protruding nodule on the end) and covering hos trach hole so he could smoke. I decided that if I smoked past 40, that'd be me one day and I didn't like the image.
