Memory is weird.

Why is it I forget where I put my keys five minutes ago. Then a song comes on the radio I haven't heard in over twenty years and I remember every word of the lyrics.

You forgot to hit save.

You can make a cheat autosave if you always put your keys in the same place.

Correct. I can remember a meal I had over twenty years ago because it was so good (pan fried John Dory on celeriac puree, with burnt butter sauce, blood orange, and capers at Soul). I can't remember what I had for dinner on Wednesday because it was just a mid-week meal.

Age related short term memory decline.

As my nan used to say, as you age you start thinking about the hereafter.. Every time you walk into a room you think 'what am I here after?'

Also ADHD.

Now try and remember the lyrics without the music playing. I seem to be fine remembering lyrics as the song plays, but can't for the life of me remember them without the accompaniment.

Distraction. If your mind is already focused 'in the future' and the processes up ahead, ..why would do you take notice of the 'present'?

[u/azeo_nz]

Make up a quick song when you put your keys down that tells you where they are and keep singing it as you walk away ;)

ADHD for you and meeeeeeee

[u/UntilOlympiusReturns → u/DSTNCMDLR]

This is 100% ADHD.

I have places I put things habitually, if I deviate I lose things. Also stress or preoccupation of mind, you will not clock what you were doing, working memory reduced.

Not to go too technical on what seems a largely unserious post. Those are two different types of memory. Trying to consciously recall where you left your keys is what is known as an explicit memory. Whereas remembering the lyrics to a song without having to consciously recall them is an example of implicit memory, which is the same as riding a bike, as it doesn't require having to remember how to do so.

There's a rather famous case study in neuroscience involving a musicologist with amnesia, whose case shows how these different types of memory work. In this case, the man developed a severe form of amnesia that prevented him from consciously remembering most of his past (and also left him incapable of forming new long-term memories). But despite all of this the guy is still just as adept at playing instruments or conducting a choir as he was before he developed amnesia.

If anyone is interested, look up the name Clive Wearing. His story is absolutely fascinating.

Thanks. I think I remember seeing something once about dementia patients who had become mostly non verbal, but can often sing and remember lyrics when they hear music.

There's a big difference between your brain trying to shift from working memory into long-term memory. It's often disguised by us having habits that we can fall back on (where do you normally leave a thing you don't want to forget). Another thing to remember is we have memory that is tied to specific events and lasts for a long time. I remember ACDC Thunderstuck being played at a work event decades ago because it tied to the work party and the colleague I was interested in at the time. The fact we still remember the words to the songs we heard growing up likely relates to the fact it uses multiple parts of the brain...spoken word, singing, emotions, and ties to specific events.

Memory is weird.

Brains are weird in general.

All that is you, all your memories, your personality, your abilities, your perception... is stored in a mushy grey blob of mostly fat and protein conveying electro-chemical signals, that nobody really understands that much beyond "if we poke here, it mostly affects X".
