It was a young lady I did a treatment on. She smoked, but that was beside the point.
When the treatment was finished I asked, "So, does your breathing feel better?"
She said, "Well, I still have a headache."
"No," I said, "Does your breathing feel any better?"
"Yes, I think my nose feels more clear."
"No, I mean your breathing, like, your lungs. Do your lungs feel any better?"
"Um, well, I guess they feel the same."
I reported this to the doctor, and he had laughed with me.
