That's actually the way to remember shit I guess.
I was listening to a radio programme (odd spelling for Starmongoose) and the guest was a guy who came up w/ a memory programme.
He teaches people how to memorize data in a short amount of time using his system. I guess he holds a guinness record for having memorized so many shuffled decks of playing cards in the order they are dealt.
So just straight up remembering numbers is hard to do, association is what really causes your brain to hang on to pertinent data
