It's never too late to improve your brain although there can be this false thinking that the brain needs "intellectual" hobbies to be healthy.

Yo give the most benefit, you should mix in hobbies like chess with things that stimulate your whole body and cause your brain to coordinate multiple systems at once. Something like dance is highly beneficial because you're not only listening to music, you're coordinating your movements, balance, emotions. If it's a social dance even better. You're coordinating your social skills as well.

I don't practice what I preach but I think social dance is the number one way to keep your brain healthy as well as your body if you're trying to be efficient.
