I do the opposite of the author. I tend to add names to the Phone contacts of people I interact with, even if briefly. Sometimes, I text/call a fixer-upper and realized that we had interacted 10+ years ago. Similar to emails, at time, I go back and reply to the same email thread from 15+ years ago. On the phone number thingy, I use the rhyme-ish way of remembering it by saying it aloud, and then using it on the phones and I remember quite a few phone numbers. Besides the numbers of my immediate family, I can dial my sister, a few friends from school and some of our neighbors (most of the number do not seem to exist anymore) back home on the keypad from muscle memory. I try to teach my kids to remember some numbers and I try and test them once a while. They do think, I’m an irritant. During School days, amongst friends, our tactics of remember historical dates were to prepend phone number patterns and associating them to the events/person etc. My wife is usually surprised when I recite phone number of recent visits to clinics, places, etc. This one are usually ephemeral and I usually forget them after a while. I like to pretend play Sherlock and look around things, remember them when visiting new places. :-)
