According to a recent study published in the International Journal of Geriatric Psychiatry, the more people over 50 engage in games such as sudoku and crosswords, the better their brains function.

Researchers looked at data from about 19,100 participants in the PROTECT study to see how often they performed word and number puzzles. Then they used a series of tests to gauge attention, memory, and reasoning.

In short, the more people engaged in puzzles, the better they performed on tests.
