Assuming you equate smarts with IQ, Green's comment castigating me for insinuating that successfully reading my last post out loud has a positive correlation to intelligence is apropos.
As penitence for my transgression a couple of links to REALLY find out how smart you are:
If you have more than 10 minutes, check out a brief history of IQ and take a free test.
If you're like me and don't want to know the ugly truth, try this memory game. Not a perfect indicator, but unlike saying colors out loud, the ability to retain information and process abstractions are indeed elements of formally measuring IQ. Let it be noted that the game doesn't measure logical reasoning and mathematical capacity.
Post your scores if you want to brag... I racked up a 56 my first attempt but couldn't get much over 40 after that.
