What numbers do you have committed to memory ??? Phone numbers ? Passwords ? Part numbers ? Model numbers ? License plates ? Lock/Safe combinations ? (multiple) PIN's ? Drivers license number ? Credit card numbers ? Zip codes ? Bank account numbers ? Ticket numbers ? Serial numbers ? VIN's ? That's a lot of stuff to remember! I've noticed that practically nobody remembers more than a handful of phone numbers anymore, thanks to smart phones turning everyone into slaves of the technology. I admit I'm guilty of that somewhat myself. But I still use a flip-phone. I could really rant on about how many brain dead zombies I've encountered, who were completely lost and clueless, when their phones went dead. But I won't. This thread is about the numbers you do remember, and for whatever reason, known or unknown. Some numbers just stick in your mind. For me it's zip codes, I have a knack for them, and I've surprised many while demonstrating this ability. I've owned over 40 vehicles in my lifetime, which includes cars, trailers, motorcycles, scooters and ATV's. I can still recite VIN's from three of the cars I've owned, one of which got junked in 1983, It's 5T09C137463 (I'll let someone google that), and another succumbed to the New England Tinworms in 94'. It died of Fe02 poisoning. I also know the serial numbers to about a half dozen of the guns I own. True some of them are custom serial numbers, but others are not, like my PPK, it's A007xxx. I also know the numbers on my Model #41 and Model #60. I used to know my drivers license number, but thanks to the new Real ID, it recently got changed. But I still remember the old number and my final Mass DL number. So what numbers stick to the inside of your brain, and don't say 867-5309.
