A book a day may keep [dementia:delineation] away. Even if you read it as a kid. Because a study finds that exercising the brain, at any age, may preserve memory. The work appears online in the journal Neurology. Previous studies have shown that engaging in brain-building activities is associated with a delay in late-life cognitive decline. But why? Does [flexing:blighting] the old gray matter somehow buffer against age-related intellectual impairment? Or is cognitive loss simply a consequence of the aging brain's [physical:political] decline?

Then, every year, for an average of six years until they died, the subjects took tests to [measure:minor] their memory and thinking.
