i can see that perspective as making sense.
Here's a different one: Because i pumped tar into my lungs on a daily basis for 20 years, i know that my lungs are somewhat "damaged". Therefore, once i decided to stop abusing them in that way, i also realized that it might not be a good idea to push them further. I believe that most smokers' lungs, and probably esophagus, are somewhat compromised already. That means they are less able to take abuse that healthier lungs and tissues may be able to withstand.
Once i decided to stop smoking, i also developed a different "consciousness" about my lungs. Now, i really want to be as kind to them as possible.
when i say my consciousness changed, i mean that that as a smoker, i was aware of the damage i was doing, but i didn't care enough to quit smoking. I knew it caused wrinkles, and other stuff. There is a certain amount of denial that has to occur when you are not taking care of yourself....it's actually self destructiveness perhaps? You know you are injesting 4,000 chemicals, you know you stink, etc. But you keep doing it anyway.
I believe that vocabulary phrase "smoke screen" aptly applies........it's like you are behind a screen or something, an obstruction that keeps you from the truth about something. "in a cloud of smoke", etc. "cloudy" doesn't imply clarity.
Therefore, when i quit smoking, i got more real with myself. So, i see no reason why people who decide to not only quit smoking, but to exercise more caution in what behaviors they engage in, should be ridiculed. I do see that here sometimes.
For me, quitting smoking was turning over a new leaf in many many ways. So no, i don't wan't to inhale antyhign that may prove "harsh" on my compromised lungs.
