Glad to hear you're doing better.
I always find it amusing when a doctor, nurse, emt, goes into the riot act about smoking. All those years of medical school and they come out sounding like an afterschool special. I mean how do they expect you to react? "WOW, I had no idea smoking was bad for you. Thanks Dr. Obvious, you saved my life."
True story: A good friend of mine who's a kidney specialist smokes cigars and eats red meat but won't drink tap water because of the contaminates.
