"And the point of talking about the FOs age was...?"
I have no idea of his age, he looked young, but then again so did I once. Not doubting his abilities, just a comparison between the age of the airframe. I would challenge anyone to think that it left Toulouse for the first time over 18 years ago.
Having flown in a BA 767 fairly recently, that DID look its age of 23 years! The FO on that flight had a grey beard, so probably a bit older than the airframe.
