I've been a 3+ pack a day smoker for 35+ years. Haven't had a smoke for 45 hours.

My father-in-law from decades ago was Herschel, yep that is how he spelled it. He was like a father to me. A hero to me. I loved that man. He smoked those damned unfiltered Camels all his life. He retired and went hack home to his family farm to retire. He was retired about 6 months and came down with lung cancer, he lasted about 9 months.
It has been many years but I well remember his passing, and standing in the hall of that hospital, crying like a baby, for all I was worth. Damn cigarettes.
