londonclubguy, it's a case of odds. You may never experience it in your entire life of flying as a passenger. Don't become paranoid about it. You probably have a better chance of winning the lottery before you experience a severe CAT event. Go to the loo (hey, even pilots have to) and take whatever you need from the overhead locker when you need to. However, it's safer to keep the odds down to a minimum (of you becoming an injury statistic), so just keep your seatbelt fastened at all other times.
