I am totally hooked on the Nintendo DS game Brain Age. Admittedly, ever since I finished college, I have not exercised some parts of the brain so much. I've never imagined how brain training can this be fun, and let us not mention how it prompted my budding love for numbers right now. That's a relationship that should have started since kindergarten. If only the DS was invented ages ago, I would not have feared numbers as much as I do now. Oh, well. Haha! I am hooked on Sudoku big time. It's not much math but a lot of logic. Accomplishing each puzzle feels great.
Nintendo DS kicks so much ass, I do not even have a faint fart of regret that I should have bought a Sony PSP.
