After Joshua Foer visited a National Memory Championship competition, he was intrigued by the way people with no special mental handicaps were able to memorize extravagant amounts of data. He dug deeper and found out that people like us could also do the same, we just needed to train our heads to use that portion of our brain for memory. By creating what he calls “memory palaces” — visions of absurd contextual episodes in our heads — we too can remember things easier. And not just easier, but more grand as well.
In the end, it’s a bit like training our minds to remember by topic rather than by words.
