Ever done this before: You are typing something - either some code or something in Word. Suddenly, you realize that you haven't saved for a long time. So, you hit Ctrl-S. Press Ctrl-S once does the trick. The screen flickers to indicate that the file has been saved. But no, you are not satisfied. With the 'Ctrl' key pressed you press 'S' around 5 - 6 times or rather keep 'Ctrl-S' keys pressed and watch as the screen keeps flickering. I do this very often - once me college asked me why do I do that. One Ctrl-S is enough. I shrugged and told him I just want to be extra sure that the file is saved. A few days later, I observed him doing the same thing Try it once. You are bound to get addicted to it.
