Airplane games

I have added a new game to my plane boarding games. There is always the game where you board early and then watch as everyone else boards and you figure out which girl you would have sex with if the plane was crashing. The new game is man or woman. I have noticed that there are many women that are middle-aged, over-weight and have very short hair cuts. Sadly you can't tell if many of them are men or women just by looking at the face. So now when I get on a plane I not only look for my plane crash sex partner but I also try to guess, by faces only, if certain people are men or women, sadly I have been wrong more than once.
