Burying your nose in a good book, or spending the morning working on a crossword puzzle could keep you mentally sharp in old age.
Researchers at Rush University studied nearly 300 older adults for 6 years, and then examined their brain tissue after they died. Each had been given tests to measure their memory and thinking and had been surveyed about reading and other brain-boosting activities through their lifetime.
They found people who did not include reading and puzzles in their daily routines experienced mental decline 50% faster than those who enjoyed those things.
