A story in today's paper confirms something I posted a few weeks back, here: Whole-body exercise is better for your mental faculties than brain-only exercise. (I must admit I want to try the new vision software that's out for the GameBoy DS.)
"So instead of spending money on computer games or puzzles to improve your brain’s health, invest in a gym membership. Or just turn off the computer and go for a brisk walk."
