Rowan Tree and Red Thread

irishkate has links to two interesting quizzes up at the BBC's Human Body and Mind section of the Science and Nature site. The first looks at our ability to discriminate genuine from fake smiles, the second our ability to recall faces we've seen and how lack of sleep affects our temporal recall of faces.

Not sure how seriously to take the results though. Either that or I'm a lot less sleep deprived than I thought I was.

(18/20 smiles, 100% recognition, 87% temporal recall)
