How long has it been since you threw a ball around?
If it’s been a while, now is a good time to pick it back up! You might start with something simple, like throwing a ball in the air and catching it. If that’s too easy, consider taking up juggling! Doing so can hone your brain’s visual, tactile, and hand-eye responses. Scientists have recorded improvements in the brains of people who master sensory-guided movement skills like this—including greater volume and density in certain parts of the brain.
