My older brother used to make me memorize random things. When he took me to practice driving, he’d quiz me on the color and type of cars around me. He’d ask me license plates of people in the parking lot or to remember long combinations of words letters and numbers
At one point, I could glance at an SSN or credit card number and remember it for a while… I can’t do it anymore, but my passwords are great. It’s amazing what the mind can be trained to do
We also came up with this stupid super long url, I still remember it decades later but he can never get the whole thing right. One of these days I’m going to buy the domain name and put something up there, it’s almost a password in itself
