well think about it, when you are in college, where you HAVE to study and do good to keep a scholership or be able to attend that university.. Students spend their time partying, studying, and eating.. sometimes they have no time to figure all that out, or even have time for anything more then that 1$ burger from where ever.. they scarf it down on their way to class, then spend a few hours in class, possibly even have a snack after class(I am unsure about others, but I would have 3 hours classes and even if I ate bfest, I'd be hungry again after class, could have been because I was preggers.. lol..) but they are so stressed out, and so busy, they dont think about things like that at times..
