4583371 my family phone number when I was a child. I am 51 now and can't remember my mobile phone number or my husband's. But I can remember my mom's phone number.
I can't remember pin for my credit card. I can't remember my internet account number for my current account.

I don't have enough bloody fingers sometimes, and yes I count discreetly.

If I have to count pages of a document for photocopy, I have to mark every 20th page with a sticky note.

We all learn coping mechanisms.

Back to the patterns thing -
I used to make little fabric applique books for babies. Numbers, alphabet, shapes and colours. No problems figuring out how to place the pages upside down , left to right etc. in proper order before stitching so that it came out in sensible order with all images etc in correct direction.
