But according to this scientific diagnostic tool, I have the brain of a 25 year old. How old is your brain?????

You’ll have to know how to read Japanese to make this work, or you can just follow these instructions:

1) Click on start. The diagnostic tool will count down from 3 and show you some numbers.

2) Remember where the numbers are. The diagnostic tool will make the numbers go away and replace them with empty circles.

3) Now click each circle in turn, in order from smallest to largest. Zero is smallest (that’s what screwed me up … for some reason my brain would not remember that zero is the smallest).

Then, the game will give you your brain age, in Arabic Numerals. Report your brain age below…

Hat Tip Ana. Who’s brain is the same age as mine, it turns out.

    We’re pretty good for humans!

    But then there’s this:

    20. Is that good or bad?

    Some other similar thing I did a few months ago said I have the brain of an 18-year old. I guess my brain is aging rapidly after years of arrested development.

    Mine said 51 and it seemed I got quite a few wrong…something must be wrong here.

    Thank you for the link.

    A+++! Would Play Again! I scored a 20… which I am!

    Scored 29, actual age 41. Should I be worried or relieved?

    It says my brain age is 23, and I’m actually 26. I suppose that means I killed off 3 years worth of brain cells by binge drinking in college.

    I got a brain age of 26, but I’m only 21… my brain is 4 years older than the rest of me??

    I scored between 23 to 28 with a few attempts. I am 24. Is a higher age good or bad?

    Oh no!! It said 40!… I’m 27… darn… never do these things too close to bedtime I guess ?

    I scored a 20. Not too bad for an old man of 47!

    29, pretty close to my actual age (but using a touchpad on my laptop made me mess up more than I probably should have). Not sure how this is “scientific” or what “brain age means.”

  14. #14 Susannah

    I’m 66. I scored 31.

    Does that mean I’m fast approaching my second childhood?

    I’m 40, spent the better part of the last 3 decades in a blur of drunken bar brawls and apparently my brain is 25.
    Maybe I haven’t completely wrecked it after all?
    I also recently took an IQ test that gave surprising results.
    Maybe I’m getting a second shot at using this poor old brain?

    i’m 18 with a 51 year-old brain? Is this really scientific?

    Score 23, Age 53

    I don’t understand – my brain age was 34 (only one off from real), but then I did it again, did worse, and it was 25. Which way is better? I would guess that somewhere early adult should be best, but what age starts the downward part?

  20. #20 Christie
    February 10, 2009

    20… which is less than my real age, so good, I guess. But I did get carded to prove I was over 18 the other day… that was awesome.

    This is one of the exercises that the chimpanzee Ai (and her son and others in the community) do. Remember the news a few years back about the chimp who counts? (See http://www.pri.kyoto-u.ac.jp/ai/index-E.htm). She also does exercises that involve associating Japanese characters with colors.

    Gotta go. Judgment Day (about the Dover trial) is being rerun on PBS.

    35, and I’m 60.
    One time the cursor was over the circle;
    one time I misread 8 for 3
    and a few times I …. hi, kitty cat … ooh, shiny. Was that thunder outside? I wonder when my honey will be ….. oops

    My brain age is 52 (highest till now), but my actual age is only 27. Anything lesser or equal to four numbers, i got it right, but anything above was wrong. I knew i’m getting old and very eager to retire.

  28. #28 wicker

    score 35, age 38.

    I guess that means I am about as old as I am…

  29. #29 ddc

    It says my brain is 33. I’m 43. But there’s no way I could have done this thing at all ten years ago. The clinic I was in back then kept me blindfolded the whole time anyway.

  30. #30 Ian Pattinson

    Scored 29, aged 39. I’ll take that to be a good thing.

    36. Which is also my real age.

    First try 40, second run 35, actual age 52. Tomorrow I’ll try it after my first coffee of the day.

    I missed the zero a couple times too, although I knewit was there. It’s interesting how perception works, with five numbers flashed on the screen, I’d feel myself thinking, say ‘0,1,3,7,umm…8?’ and know where the 0,1 and 3 were and have no idea which was the 7 and if it really was an 8. I’d have to see all the numbers to know which were the smallest, but I’d only pay attention to the smallest ones in the time alloted.

    I scored a 26 (My driver’s license says I’m 43). I like to think that I don’t ‘act my age’ (whatever that means). I play video games a lot, and listen to a wide variety of music, new and old. I know I certainly don’t feel my actual age.

    out of 3 tries: 20, 25, 25
    actual age: 25
