David: My Brain is 50
At least according to this morning's check on Brain Age. That's up 3 years from yesterday, but down 5 years from my initial check on Wednesday. I blame it on the handwriting recognition misinterpreting my "4"s 3 times.
Other than the occasional frustration of the software's inability to translate my hastily scrawled numerals, I'm really enjoying this DS card. My wife has also started a file on the card, and the game does things like forcing you to draw a koala bear from memory, and then comparing your drawing to those others have done of the same subject. All in all, I think it's already been worth it's $20.
Plus, solving rapid-fire arithmetic is oddly entertaining.
