This document discusses brain training and ways to improve cognitive abilities. It explores whether brain training games can actually make you smarter or improve skills like focus, learning, and memory. While brain training games may improve performance on the specific tasks practiced, the evidence that they enhance abilities in other areas of life is mixed. Reading books regularly may be more effective for developing cognitive skills and gaining knowledge than brain training games. Spending time doing physical activity or reading provides cognitive benefits and allows the brain to form new connections.
