About the "vocation" factor. Well, i would have LOOVED it if they had analyzed our vocation. That would have given some of us such great advantage. I know you guys out there, spending hours in airports just for the sake of feeling at home, and watching and staring, sometimes even letting a tear fall. Also those of you who have made flight simulator the second most important thing in your life for how helpful it is when for when you study Instruments, and for when your friends prefer to play play station as well. And what about those who have the superpower of boring their families and friends, and can't even conceive why would someone not love this whole thing. Ever since we where little little little, ever since we can even remember.
