1. Finish a crossword puzzle. Just like a walk exercises your body, puzzles give your brain a workout. Think how satisfying it is to fill in that last clue.
2. Pick up a book. Whether its the latest novel by your favorite author, a new historical work, or a how-to book, reading keeps your brain active and nimble.
3. Try your hand at bridge. Or if youre already a mean bridge player, keep it up. Card games provide ideal mental exercise as the brain ages.
4. Become a social butterfly. Well, maybe not a butterfly, but turning off the television and interacting with friends and family will keep your brain young.
5. Have a brain-healthy diet and exercise plan. This includes eating lots of dark-colored fruits and vegetables which are thought to slow the brains aging process, limiting fat and alcohol intake, and exercising which will also keep dangerous stress levels down.
