If I read something my brain stores keywords/phrases to it anywhere from 30min to years. Sounds super normal (I think, least for 30min), but this has served me really well in two areas.

1. Tests. As long as it’s a knowledge test and not a skill test I can skim read right before (even if it’s like 100 pages and I didn’t learn any of it before) and pass (for multiple choice grade is usually in the 90s, write-in is more 80s). Only professional place I use this outside of school is the bullshit PowerPoint “training” at work that makes you take a test at the end… (I don’t work an office job, idk might be more useful there)
2. Online message chats. Great for looking stuff up like birthdays or preferences or someone told me something specific a year ago and now wants to talk about it in-depth and I have to go refresh on the exact health conditions of their dog while they’re grieving to me (I mean I could ask for a refresher, but when a friend is needing a comforting ear I’d rather just search it up quick while they type instead of making them back track their narrative which when you feel upset feels really alone someone can’t be right there in the moment with you off the bat, just a small way to care for my friends). Mainly though I do text DND and it’s amazing there lol. Had an unintentional tpk and offered a restart with memories (deus exmachina literally time rewind) which my group was into. I’m like shit we’ve been running this campaign for years, how am I going to remember the exact fight setups, initial NPC reactions, etc. I had a very specific search phrase for every event memory logged and made the whole thing a breeze to re-do literal years of content. And tbh I think I enjoyed it even more than my players cause I’d go back and reread their early murderhobo days and then get to freshly compare it to their evolved anarchist present (…I mean they were still murderhobos, but brought a tear to my eye to compare they’d learned some principles and loyalty lol).
