Those nurses were right on the money. Good for them! Emphysema is a killer from which there is no escape. Being in a nuring home isn't any fun either with the continual invasive poking and probing into one's body. Ugh. Your mother-in-law was allowed to spend her last days puffing away in some peace.
My aunt died from lung cancer, smoking 3-4 packs a day.
In the last months of her life the hospital wouldn't let her smoke. How stupid, useless and mean was that?
She was finally sent home to die. She smoked away those last weeks. She even bought a new blouse. I loved my Aunt Ginny. I miss her still.
I never have understood that mentality about the dying. Nurses and doctors would even have the dying "watch their diet." Completely unclear on the concept.
Well, one of his few pleasures left was his daily dish of ice cream. After a month of him sulking, we ditched the cholesterol meds and started serving him ice cream once again. He died of pneumonia 2 years later. So, the doctor would have him miserable for two years for some trivial thing that didn't cause his demise anyway.
Even if we follow all of the health NAZI's advice we still won't live forever; it will just seem like it.
