There are many aspects of aging you cannot prevent, but surprisingly, memory trouble is not one of them.

"The dogma for the longest time was that adult brains couldn't generate any new brain cells.

"But the reality is that everyone has the capacity to develop new cells that can help enhance cognitive functions."
