I always found any notams from BASI aka CASA along with airline manuals were best kept in the dunny, reading any of them removed any problems with constipation, as the whole thing normally gave you the sh$ts, and so removed any chance of you having to buy a over the counter remedy. It also hastened your removal from said room, as normally your daughter (s) has said occupation of that room around 23 hours a day (or so it seems) so ending family disputes (of which you had no chance of winning anyway) so they do have some purpose, they are also good for holding old spare grog fridge door in place, one of my TAA old manuals has done that job beautifully for some years.
