In May 2016 I had a major heart attack - long story short; died, but resuscitated. Complicated open heart surgery followed (CABGX4) now on the mend. Fortunately I had given up smoking for almost five years (after being a chain smoker for Fifty five years). The only reason I made it through was that my systems had had enough recovery time after five years, for me get through it all. So Quit now to start putting some brownie points in the bank - smoking WILL kill you, so your only hope of survival is how well you can recover from being a smoke. I sincerely hope you have enough time to make a difference.
