Oh, study. I didn't know people actually did that, as long as you stay awake for most of the class, you can almost always get 95% or higher on tests without studying or doing homework, especially if it's multiple choice, in which case it's hard not to get 100%. The only test I've studied on has been the Economics final, and that's because it's an AP class where he's told us that most things on the test will not be covered in class.
Eh, the only reason I would ever become a vegetarian is if meat became more expensive or if there began to be a food shortage (eating at lower trophic levels is better as long as you get your protein from other sources). However, without cheese, I'd probably be in the hospital right now being treated for malnutrition. Since I hate food though, if I could eat less vegan food and gain more weight, I'd do it. I just wish science would come up with food in pill form already.
Or Solvent Green, that would solve many problems.
