Interact...

It has been proven that individuals who rarely talk and interact with others will suffer from negative impacts in the brain. 

This is because when one is not actively engaging in conversation, the brain cells tend to become dormant causing the brain the shrink. 

However, if one is participating in an intellectual discussion, it is assisting in expanding the mind with knowledge. 

This is essential for brain development and growth as processing information and thinking, as it is similar to our brain as exercise is to our bodies. 

The deeper the thought process, the more the brain muscles are used, and the better the brain develops. Reading a book is recommended to keep the brain active.
