What Do You Have Memorised?

I have a thing with numbers so I know most prices of what I usually buy in supermarkets. And as it's all going up lately I know how much it's gone up and what the current price is vs the old one.

I as also remember birthdays of kids who were at school with me (and I haven't seen in decades) and all landline numbers and, addresses of my family in France (that I don't use much or for some ever)

National Insurance No! Not sure how or why I memorised it though.

I don't remember much I find I blank alot out. I do still remember my address from when I was a kid and phone number which is useful as my parents haven't moved address or changed the phone number.

The registration of my first car, my NI number and for some peculiar reason my hospital id number. Only for my most visited hospital

Date of my very first job.

I'm a Calendar, I remember most things,especially everyone's birthday,how old they are,events from old..Family & friends always comment on my ability to memorise events..My older sister said in our Family Chat group earlier this year..Who needs a Calendar when you have a Jan!!

All my home address from childhood to where I live now and my national insurance number.

I can remember some birthdays of kids at school I don't talk to. Can't remember the birthdays of those around me that I mix with

I actually still remember a friend’s home phone number from about 20 years ago. His family no longer live in the house and i’m no lingering in touch with him so it is fairly useless info

I remember when we were younger we used to answer the phone by saying our phone number, not sure why and why we stopped. If you are of that era that is probably why you still remember.

National insurance number, and when I got a speeding ticket and no car insurance

I remember my date of birth, that's about it lol, I've had the same phone number over 10 years and I never remember it when asked

I have phone numbers national insurance number and my bank account numbers memorised

Increasingly less

Most of the things I have memorised are random nonsense, only good for quiz nights etc.

Bank card number.

Passwords.

Off the top of my head, mobile no, NI no, bank ac and sort code, dob, family birthdays.
