Are you kidding me?
This is the internet, bucko.
There are dozens of sites with HUNDREDS, THOUSANDS of quizzes, mostly for lame 13-year-olds to post on their livejournals. True, the lack of advertising is confusing, but I honestly need no better explanation of internet behavior than, well, they just fuckin' wanted to.

This is the creators business website; http://leeterwal.com/

He says on a Flash Developer resource site, "I am getting really into Brain Games and Brain Training." So I guess this was a Flash practice exercise, in a subject he's been studying.

Of course all these quizzes on the net are strictly for fun.

@Flint, go pound this. :p:

Yay! Sober, my brain is 10 years younger than my body.
But then I also had the advantage of playing it again. I did not sit there all furrowed-brow over the anagrams, as I knew that the letters have to show blue to count. I am rubbish at anagrams, but even I can manage four letter words as long as I get the rules.

Also I did not have the busiest photo in the world as my first spot-the-difference.
(Fourth of July I think - so much going on!)

Oh and did I mention I was sober ;)

Brain age of 27. Not too bad, but then I'm a big fan of brain puzzles and stuff like Kakuro.

The anagram one messed me up a bit though. If you didn't move the letters into JUST the right spot, it wouldn't count it. Lost some time trying to get it to recognize my entry.

I liked the yellow stars. track ball, baby, 29 clicked.

eta: got stuck on anagrams. COIN.... what was it? I STILL cant get that.

icon?

d'oh!

Yep, those yellow stars were annoying. But my 45-year-old self somehow managed to score 30...after three drinks at happy hour. :beer:

34 and I'm 45

I got stuck on the spot the differences between the pictures when the inauguration picture came up. I stared at that picture for a good 40 seconds and never found the difference. I don't believe there was one, since they didn't show me the answer. I got something like a 70 for a brain age on that part of the test.

I had a total brain fart on the anagrams. Bizarre, given I am usually quite good at wordy stuff.

My brain is 26. I am 21 years older than that.

I freaking rock.

This is your brain, 47. This is your brain on trackball 26. ;)

The star clicking was actually my worst one.

And I agree with it being hard to get the stupid anagram letters in the right spot...

So probably, if you consider outliers and stuff, my brain is actually 12.

it gets younger with practice

You're right!
