Okay. Stop whatever you’re doing, stand up and clear a small space.
Now stand on one leg, “flamingo” style, with your eyes open.
Finally, count how long you can keep your balance like this for.
How long did you last? Because if was less than 20 seconds, the news might not be all that great.
According to this article in The Independent, researchers from the University of Tokyo challenged more than 1300 men and women with an average age of 67 to stand on one leg with their eyes open.
Those who couldn't do it for more than 20 seconds fared the worst on tests assessing cognitive function. The test could also determine how susceptible you are to suffering a stroke.
These people were also more likely to have cerebral small vessel disease, a condition where tiny blood vessels deep in the brain are damaged. What's even scarier: participants didn't show any cognitive symptoms or problems before they were tested.
Study lead Yasuharu Tabara concluded that “one-leg standing time is a simple measure of postural instability and might be a consequence of the presence of brain abnormalities.”
NOW ... after possibly scaring the bejesus out of you (or possibly saving your life), let's test out your brain in a different way to see if you're left or right-brained.
