To see a world in a grain of sand
Or a heaven in a wild flower,
Hold infinity in the palm of your hand
And eternity in an hour.

Brains are muscles.
They grow strong with exercise.
And even if they're strong, they grow weak without it.
In the months before Kasparov lost to Deep Blue,
his mother came after him.
She was worried that he wasn't spending enough time
exercising himself (on chess).
Her worries proved well-founded.
