In 2009, I set the record for the most numbers memorized in 5 minutes in the USA. I did this when I became the 2009 USA Memory Champion.
I memorized a 167 digit number. Since then that record has been broken but I believe that I can break it and get the record back one day. This video below explains the method that I use for memorizing numbers
Memorizing numbers can be impressive even if you are just memorizing a 50 digit number for friends or setting new records at the USA Memory Championship.
