I’m 44 and I can remember my best friends phone number from 5th grade. Couldn’t remember it when I was in 5th grade and I can’t remember any actually useful numbers today, but I know that one. A guy named Jeff has it now. He’s nice.

Yup. One time I used it for a password. Then forgot that it’s what I used for the password, until I reset the password to something else… But I still remember the key.
