Just as physical exercise strengthens your body, mental exercise enhances brain function and reduces the risk of cognitive decline with age. Engage in strategic games like chess or bridge, and word games like Scrabble. Solve crossword puzzles or number puzzles like Sudoku. Read challenging newspapers and books. Develop the habit of learning new things, such as recipes, driving routes, or a musical instrument. Enroll in a course on an unfamiliar subject. The more you stimulate and engage your brain, the more you’ll continue learning and reap significant benefits.
