In hospital for a minor operation. A nurse asks me to fill in a questionnaire, detailing any medical conditions I might have. I say that I am allergic to cats. On learning this, the nurse writes the word CATS on a large, red label and attaches it to my wrist. This, she explains, is to warn the anaesthetist of my allergy.
I imagine the scene as the anaesthetist looks down at my comatose body, spots the warning label, sighs, and regretfully instructs his assistant to remove Fluffy from the operating theatre.
I wonder if that's why hospitals are so often after funding for cat scanners.
