I read a few of those a few years back, and put the memory palace method to the test. I was able to easily recall all twenty unrelated items I placed at stops along the path through (one of) my childhood home. "Why is a jar of pickled onions in the mailbox?" "Wtf, an accordion on the driveway!" "Who left a beach ball on the front porch?" Etc. Those are only examples, as I also used the method of putting an identical object in every stop to "erase" the previous contents (an oversized lacrosse ball). I had to walk the route a few times to get the erasure to stick. I wanted to move on to the ability to memorize a deck of cards in order, that would be an awesome party trick. But now in my 60s I've lost interest in impressing at parties.
On moving to Colombia I discovered men's jeans made of the same stretchy denim looking fabric as for ladies with dangerous curves for their skin tight look. b Not skin tight fit so I almost never get my junk squished in 'em. Quite superior.
My eldest brother is by far the most accomplished mind of us and though we all have good memories, he really studied memorisation techniques formally as you describe. No winging it for him. Perceiving what has been removed or moved from/in a scene is actually the only memory trick I tried to improve. In my wildlife work it was very essential to keep a track on a lot of stuff, not the least has a beastie with big teeth that you could see become one you cannot haha. Its something few pay attention to but I found it incredibly useful for my reading of charts. I could notice indicators repainting and such, others I have tried to teach trading were completely blind to this and more. I'm the same with parties, my tricks are not that good compared to the young ones. My daughter is an incredible dancer*, when studying (not dance) in university she started a small company doing choreography and for a while she was recognised as one of the best "shuffle dance" of all things, instructors in California. I can't even shuffle dance anymore, which used to really surprise people much because of my size My knees are buggered. *she has always been able to see once and copy even complex dance routines.
I just watched that movie "Doom" with Dwayne Johnson et al. Never saw it before, but oy, that brought me back. Shitty movie, but I liked how they went FPS perspective toward the end on Karl Urban's character. So Dest, are you saying that if SHTF, you will be doing something similar? Live-streaming your FPS of assholes? Please provide that link if it goes down!
You mean the violence of antifa and blm in 2020? You are stupid, how did you get so unbelievably dumb?
Yeah, I should have done the most rudimentary cost-benefit analysis beforehand. It's too late for me. Save yourself.
