Previously, we learned how natural brain deterioration is mostly caused because of disuse. If a neural pathway is not activated from time to time, it will slowly diminish in strength until the memory is no longer recoverable. Having a rigid daily routine is a sure way to make sure your brain doesn’t have to think very much. To keep your memory intact, make sure that you use it on a daily basis. Vary your routines, do the crossword, or try memory games to keep your brain active.
