I think that maybe it is just something that takes my mind off the pain for a few minutes. I am a covert smoker, and sneaking around trying to avoid my parents dropping in of the neighbor kids seeing me out keeps it interesting. I also enjoy smoking and having something to do with my hands other than stuff un-needed food in my mouth. I can no longer crochet or do any type of needle work any longer. Anyhow this is just my opinion and you know what that is worth, Lisa
