People of Walmart.
My brother-in-law died of a hereditary form of lung cancer. We (the siblings) took turns staying with him at the cancer treatment center in Oklahoma. What dumbfounded me was the number of folks who were having a smoke prior to boarding the shuttle bus to the treatment center where they were, apparently, trying to prolong their lives by radiation and chemo.
I've always admired folks who have quit smoking and stayed the course as I find it near impossible to maintain any semblance of a healthy diet, something I think is much easier to accomplish than smoking cessation.
In my practice of approximately 10 total providers, we typically lose a patient every year, might stretch it out to 2, from fires while wearing oxygen caused by smoking.
In fact 2019's winner actually set herself on fire while wearing O2 a year or so prior. Spent months in the hospital, ICU care, transferred to a burn unit, only to do it again in 2019 and not survive that event. Didn't even make it to the hospital this time.
If we stay late after work for meetings, Etc and walk out into the parking lot after all the patients have left for the day, you would be amazed at how many cigarette butts are just lying around.
Just have to look at it as an addiction. No different than meth, crack, Etc.
I too struggle with eating correctly.
