Something's up

For the first time my doctor didn't yell at me to quit smoking, just to cut back. I may be a lot of things but I don't think stupid is one of them. My heart/lungs are working well. No COPD. No congestion. No coughing. The rest of me is falling apart. I have a feeling they suspect something but aren't telling me until it's confirmed. A periodic cigarette helps reduce the pain in my legs. I wasn't offered pain killers. Just told to cut back on smoking and quit eventually.
