Smoked from 15 to 52. Pack and a half a day. Heart attack at 52. On seven IV's and they thought I aspirated something so they cleaned my lungs out. Was on a ventilator for the first twenty four hours. Went to the ER about 9 on a Friday night. Next thing I remember it was Tuesday at 10. Ended up with one stent on the widowmaker. Had no desire to smoke when I got out. That was 17 years ago. Mom and Dad both smoked. Mom until she was about 74 and had lung cancer. Part of a lung removed, but she lived to 85. Passed away with COPD. Dad smoked a few more years, but he lived to 89.
