Many of us will have heard the saying, "You can't teach an old dog new tricks." It's fortunate then, that science tells a different story.
It's true that our brains do change as we age. But they do not lose the ability to learn, they just learn differently. One study found that older adults just use different parts of the brain when it comes to learning when compared to younger people: rather than relying heavily on the hippocampus, which is the place in the brain that new memories are formed, older adults draw more on the prefrontal cortex, which is responsible for problem-solving and decision making. So while learning may sometimes look different in later life, the capacity for learning remains.
More recent research is also challenging the idea that ageing automatically means our brains decline. A 2026 study tracking thousands of older adults over more than a decade found that many participants actually improved in their cognitive functioning over time. What determined this? The people with positive views about ageing were more likely to experience these gains. So, negative views on ageing might act as a sort of self-fulfilling prophecy - if you believe your brain functioning is going to decline with age, it likely will.
Researchers increasingly understand the brain as being adaptable throughout life. This is known as neuroplasticity, and it allows the brain to form new connections, strengthen existing ones, and adapt in response to new experiences.
So perhaps instead of asking whether you're too old to learn something new, maybe you should start asking what it is you'd like to learn next!
Ways to keep learning at any age
Follow your curiosity
Learning doesn't have to happen in a classroom (though by all means go back to the classroom if you so wish!). You could explore a topic you've always been interested in, listen to a podcast, watch a documentary, or research your family history. Many community organisations, libraries, universities and online platforms offer courses designed for lifelong learners. The social side of learning with others can be just as valuable too.
Try something new
A new hobby can help stimulate the brain - whether it's painting, photography learning te reo Māori, woodworking or playing an instrument, new challenges encourage the brain to build new connections.
Stay connected
Conversation, shared experiences and meaningful relationships all help exercise the brain. Joining a club, volunteering, or simply catching up regularly with friends can provide social and cognitive benefits.
