I was in a speciality clinic recently and the doctor tapped his pen on a piece of paper. My blood work showed significant problems with my liver.
He said "Either you are drinking yourself to death, or you have hepatitis."
I blinked. "Um, well, I don't drink, so I guess we can go with the other hypothesis. Or wait, maybe I had it? No. Yes. Definitely. I remember, I picked it up in the hospital in the middle of the cancer years."
The doctor started taking notes. "Which kind? A, B, or C?"
