You can totally play Tetris in your head
(lemmy.world)
A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
My favorite tetris fact is that it may help with PTSD flashbacks. Link for the curious.
Since learning about this, I have decided to keep the game installed on my phone in case something wild happens (I'm thinking after witnessing an accident or something). It is sort of comforting to have a scientifically backed up mental strategy that is easily accessible, even if it's not a lot. I gather that tetris keeps the part of your brain responsible for looping images occupied with, well, tetris.
