So i'm taking a day off from the project again so i can copy the code in a book i just borrowed.

I'm making time for this because the name of the first chapter is "Making fish swim in the Multithreaded aquarium." and i believe this chapter will teach me about threading practices so in the end i'm researching how to make the game better. This is something i know how to do but I don't understand really why I should or when i should use it.
