Letterman's Brainday
What do you give the hilarious talk show host who has everything? If you're Nintendo, you give him the mental training he needs to stay at the top of his game.
For his 60th birthday (!), "The Late Show" star David Letterman got a special present from Nintendo -- a copy of the video game "Brain Age," and a Nintendo DS hand-held console on which to play it.
"Brain Age" works out your gray matter with a variety of brain-stimulating activities specially selected by Japanese neuroscientist Dr. Ryuta Kawashima -- including memorizing words that appear on screen, quickly performing simple math problems, reading classic literature as fast as possible, plus everyone's favorite number game, Sudoku.
Nintendo even sent Dave's mom a version of the game so they can see who's sharpest in the family. Expect a "Top Ten Reasons Why Dave's Mom Beat Him at Brain Age" soon.
