people with extraordinary memory skills compete in a unique event called the World Memory Championships.
The tasks they are required to do require tremendous power of memory retention: looking at and reciting a two-page poem; recollecting a page of 40-digit numbers; remembering the order of 52 cards in a deck; memorizing the name of 110 people after looking at their pictures; and several other demanding tasks.
Completing any of these tasks may not seem feasible for the average person, but scientific evidence seems to show that even someone with average skills can, through training enhance his or her memory skills and be transformed into a memory champion
