Well, herein lies the prejudice of the creators. For Brain Age, the ideal is 20, which is the lowest, indicating the "youngest" brain condition. I think what they're after is a concept as opposed to an "aging brain", which we all know well in the US, anyway. It's the same with this game. I dug a little deeper to the bottom of the page, and found the translated version, which is worth just reading for the translation: English page Here's a snippet: There is training to activate the brain besides the memory momentarily and to make it rejuvenate. Much better ones on the page.... There are also links to more games, which I wondered about since it did say "Part 1" by the title. Enjoy! :0)
P.S. So Faldage, I take it you didn't get a 20? ;0)
