*The surgeon or anaesthetist is on day 20 of a 20 hr a day fast, hasn't been sleeping much because have a distended stomach/eating at a strange hour, they've not eaten for 18 hours so far today. How happy would you be?
I would say that's a pretty incompetent surgeon. Which is why most Muslim doctors wouldn't fast before surgery. They would break fast and make up for it later, or schedule the surgery for first thing in the morning. etc.
They're Muslim, not fucking stupid.*
Yup.
Air Crew are also generally inclined to leave their fasting for when on leave, or if they can't do that - they just don't fast and pay their dues.
