Well said! I don't fly often, but when I do, apart from on visits to the toilet, my seatbelt remains fastened to a various degree of tension at all times. I'll trade 12 hours of mild discomfort on a flight to UK against the risk of serious injury or death any day. Anyway, squeezing my 6 feet frame into the space between those seats, most of the time I hardly notice if the belt is fastened or not.
