'Stop being so tight assed and live a little folks
It's being 'tight assed' that enables the airline industry (generally west of the Gulf) to enjoy its enviable safety record that 'tight assed' professionals have strived to achieve. With that attitude your cutting the odds on ever making the 'old' bit of the 'old and bold aviator'.
Why anyone would want to shut down all engines before coming onto stand is a concept beyond my comprehension.
Tight assed - you bet, as and when required - assuring a long and accident-free career to date.
