Where Got Hot Brains?

Let's face it: In this age of software developers becoming rich, and people doing sudoku for fun, being brainy is Hot. So what better way to increase your Hotliness with some brain-boosting exercises from the BBC?
These good people, who just a few years ago tested our I.Q.s, as well as whether we our brains think 'male' or 'female' (we failed miserably at trying to trick the test results), are back promising that in just seven days, we can have better brain-power, with their 'Get Smarter in a Week' challenge.
Give it a try! Seven days is shorter than any diet's ever promised, and what's the worst that can happen- you suddenly lose interest in watching SpongeBob SquarePants?
