Sorry but I am one of these infuriating passengers who hardly ever watch the safety demonstration.
But then I fly between 120 - 150 times a year for my job (non Airline), I could give the safety demo.
However what I do is try to get a seat at an exit, if not possible I always work out my escape route, ie nearest exit with fewest people between it and I.
I always keep my seat belt fastened when seated
However I did fly EDI - LHR last week and the captain did make an amusing announcement which did cause me to watch.
Whatever gets you through the day
