Dr Kawashima’s Brain Training - How Old is Your Brain?
 

You see, I’m playing this new Nintendo DS game, Brain Training, and it’s actually reversing the effects of age, diet, booze, poor sleep patterns and general laziness on my tired old noggin. That nice Dr. Kawashima tells me so, and he should know, being one of Japan’s top experts on brain analysis and imaging, and the author of a range of best-selling brain training books. The good Doctor has established ways of testing the current state of my brain, and exercises to put it back in working order. And because it’s a game, it doesn’t feel like any work at all.

its just more proof Nintendo knows what they are doing
