By the 3rd pack you've probably lost the lighter in the cushion of the patio furniture and dropped the matchbook in the hot tub.
If you ain't lighting a new one off the end of the last one, you are doing it wrong.
At Navy Nuclear Power School we were given 6 hours to complete our final exam. No multiple choice, everything question is either draw X system including all components (pumps, valves, heat exchangers, regulators, IC interfaces, etc) or explain a particular design parameter, safety feature, material considerations given to components due to corrosion or radiological concerns, etc.. Everything is required to be answered fully and with damn near perfect 4.0 verbatim regurgitation of the operating and design manuals. If you get less than a 2.8 you're thrown out of the program after spending a year and half getting to this point.
I smoked a full carton of cigarettes starting at 2pm when I finished the exam and used only one match. I chain smoked an entire carton of cigarettes waiting for them to post our final grades at 7pm. Worst 5 hours of my life, even worse than waiting on the cancer diagnosis. That stress was real and while those smokes kept my nerves somewhat in check, there probably was a much healthier way to go about it.
I really can't give Rants too much shit for smoking as I was addicted for the better part of 2 decades myself. I just want for him to do better than me.
