If they pounded rocks, they'd just get a headache...

If this doesn’t leap off the page at you, you’ve just been walking through life not paying attention. :-) “Our daily life is mostly, made of cases in which we lose money and/or time and/or energy and/or appetite, cheerfulness and good health because of the improbable action of some preposterous creature who has nothing to gain and indeed gains nothing from causing us embarrassment, difficulties or harm. Nobody knows, understands or can possibly explain why that preposterous creature does what he does. In fact there is no explanation - or better there is only one explanation: the person in question is stupid.” So writes Carlo M. Cipolla  as he explains the third of his BASIC LAWS OF HUMAN STUPIDITY. Read the whole thing. There will be a test. In fact there will likely be several. Daily. For the rest of your natural born life… *sigh* h.t. Jerry Pournelle's Current Mail.
