My brain became such a machine in this past 3 weeks. I became a thinker and overthink everything pretty much a lot. Its always "why" or "how" spinning in my brain for 24hours. Suddenly everything has a huge question mark on it and yelled at me to answer it. Once I ever read that human's brain can save 5 times more information than a set of encyclopedia. I assume that's not true. My brain was overloaded for trying to understand everything, yet still many questions I can't answer. But isn't it funny that the brain named itself  :)
