Brain Power - Gauge your Memory

The human brain cell can hold 5 times as much information as the Encyclopedia Britannica. Or any other encyclopedia for that matter. 

Scientists have yet to settle on a definitive amount, but the storage capacity of the brain in electronic terms is thought to be between 3 to even 1,000 terabytes. The National Archives of Britain, containing over 900 years of history, only takes up 70 terabytes, making your brain’s memory power pretty darn impressive.
