BBC’s Science and Nature section has some useful information and quizzes on human body and mind. We just stumbled upon one such test and thought we’ll share this with you.

Sleep Dash

Sleep Dash is a flash game to test the effect of tiredness on your reactions. Play Sleep Dash and then have some tea or coffee, and then play it again to notice the difference in your reaction times.

Try Sleep Dash here. It looks like just another flash game, but its fun and education all the way.
