My wife and I bought a GameBoy for our son when he was in his early teens, some fifteen years ago or so. Phil is out of the house. But the GameBoy has remained with us and is far from being exiled to the Island of Unwanted Toys. Many a night while watching the evening news or catching something else on the tube, my wife and I play Tetris.
Now, comes evidence that this addictive game "may boost the size and efficiency of parts of the brain." I wondered what accounted for the enormous increase in the IQs of my wife and me over the past fifteen years. Now I know.
