The miracle is that your brain is dynamic and continues to be shaped and to develop. It has plasticity. As such, there is no finite capacity or limitation. In this way your brain is very distinct and actually much superior to the fanciest of all computers because computers will always have built in limitations and finite capacity.
Research has found that keeping the brain active helps to build brain or cognitive reserves. This is the brain's ability to create new neural pathways and connections that can be used as a sort of 'brain savings account', allowing you to draw on this account at a later date. Studies show that many people continue to operate at a high level of functioning throughout their lives by building these brain reserves.
Your dynamic brain is shaped by environmental input across your lifespan, beginning in the womb. There really is no critical period of brain development unless one considers life itself to be the measure. The variety, diversity and complexity of stimulation that your brain receives can make a significant difference regarding its health. You do have some control and this is great news!
