Our brains are remarkably changeable. We can grow new neurons and extend the life of existing ones through changing our thought processes and adapting our behavior.
Understanding the plasticity of our brain means that we have the ability to overcome psychological disorders and recover from physical injury.
Don’t get old, get active.

To keep your mental and physical faculties in check, choose something challenging like picking up a new language, joining a Tai Chi class, or learning a musical instrument.
