Well, you can start your stopwatch and count the seconds before someone brings up the old favorite 'fatigue' again!
I flew for thirty years and never got 'fatigued' - a bit tired sometimes but every working person does at some time or other. I know of no other job, many far more physically demanding than airline flying, where people are so quick to whimper that 'fatigue' word. In fact I think I've only ever heard pilots use it... (civilian pilots, that is)
