10 Brain Games That Actually Keep Your Mind Sharp After 70
The brain fitness industry is worth billions of dollars, and much of it is built on shaky science. Those brain training apps that promise to sharpen your memory and prevent cognitive decline? Most of the research supporting them is funded by the companies that sell them. The truth is more nuanced — and honestly, more encouraging. Because the activities that truly keep your mind sharp are often free, enjoyable, and available to everyone.
Number one: learn a musical instrument (or pick one back up). Playing music engages more areas of the brain simultaneously than virtually any other activity. It strengthens connections between hemispheres, improves memory, and enhances executive function. You don’t need to become a concert pianist — even simple songs on a keyboard or ukulele provide significant cognitive benefits. Number two: do crossword puzzles and word games. The research here is actually solid. Regular word puzzle engagement is associated with cognitive function equivalent to being ten years younger.
Number three: learn a new language. Bilingualism is one of the strongest predictors of delayed dementia onset. Even beginning to learn a language — practicing vocabulary, listening to foreign language podcasts — creates new neural pathways. Number four: play card games and board games. Bridge, chess, Scrabble, and even simpler card games require strategy, memory, and social interaction — a cognitive triple threat. Studies show regular game players have 15 percent larger brain volume in regions associated with memory.
Number five: cook new recipes. Following a complex recipe requires reading comprehension, math, sequencing, multitasking, and sensory engagement. It’s a full-brain workout disguised as dinner. Number six: engage in regular conversation. This is the one people overlook. Meaningful social conversation — not just small talk, but real discussion about ideas, memories, and opinions — is one of the most powerful cognitive exercises that exists. This is why daily check-in calls that include real conversation, trivia, and storytelling are so valuable.
Number seven: take different routes. Navigating unfamiliar paths strengthens spatial memory and hippocampal function. Walk a new neighborhood, drive a different way to the store, explore a new park. Number eight: write by hand. Journaling, writing letters, or even copying poetry engages motor skills, language centers, and memory in ways that typing doesn’t. Number nine: do jigsaw puzzles. They engage visual-spatial reasoning, short-term memory, and pattern recognition all at once.
Number ten: teach someone something. Explaining a concept to another person is one of the highest-level cognitive tasks there is. It requires deep understanding, organization of thoughts, and real-time adaptation. If your parent has expertise in anything — gardening, cooking, history, woodworking — encourage them to share that knowledge, whether with grandchildren, neighbors, or through a community class. Their brain will thank them for it.
