Your Brain Rewires Itself

Your brain is not fixed hardware. Every time you learn a skill, form a habit, or recover from an injury, neurons forge new links and let unused ones fade. This lifelong rewiring is called neuroplasticity, and it does not stop in childhood.

That is why practice physically reshapes you: repeating an action strengthens the exact circuits it uses, making the action faster and more automatic over time. The same flexibility lets healthy brain regions take over jobs lost to damage, which is the foundation of stroke and injury rehabilitation.
