I've been Gematria since I am 6yo.

e.g. As a 48yo, I remember about 24 ATM PINs for many cards I had over the years, since they are all funny and memorable 4 letter names / words.

I started it as a person told my father his phone number (6 digits as Gematria that translate to "a cloth in my mouth")
