How old is your brain?

                                         This is a very interesting Japanese test.

     It is known that the age of the brain does not always correspond to our actual age and the brain quicker grow old if you are not practicing. Of course, there are many other factors that influence its aging such as stress and bad habits - for example, smoking.

     First you will see the numbers you need to remember. Then, circles will appear to hide the numbers. Click on the circles in ascending order to find the numbers. With each correct answer you will receive an additional number to proceed. Every time you fail, a number will be removed.

     In the result you will get a number that is ``age of your brain`` .

     Please put your results in the comments :-)
