I realise your post is toungue in cheek Mince, but I can easily remember the days when I would check in for a long haul flight to be greeted by a weary looking FO (paired with me, the other two crew would be in the bunks), who would be the first to fall asleep, given the chance. Me, the 'old fart' had managed to grab a few hours peace and quiet in the afternoon and have some worthwhile rest, the FO, on the other hand, didn't get any rest due to having a young family!
