You must remember that some of us, would have woken up at 1230 am for a 3 am departure. Then there are those who leave at 9 pm for a night turn to India landing at 5 am. They often then sign on at 7 or 8 that same night of the arrival for a further night flight to the sub continent. Do up to 20 days of that a month and you have an A330 Captains roster.
You will find that you will also look like you have been buttboned by the monster that raped New York.
