I am learning an instrument as an adult and my instructor commented “You’re so good at recognizing patterns.” That comment hit way harder than it had any right to.
Reminds me of one of mine. In the middle of my lesson, my instrument teacher paused to ask me some questions: can you tie your shoes without looking? Do you have trouble unlocking your door in the dark? Etc. Turns out I have little to no muscle memory lol.
Holy crap is that a thing? I have to pay attention to stuff like that - I will be brushing my teeth and it seems awkward and I'll realize I'm using my non dominant hand.
Though my feet do point reflexively when I jump or kick, and arm positions for dance I can feel still, large motor skills my body remembers.
ETA I've been thinking about this and don't think the right/left thing is the same, because I can touch type without looking on a real keyboard. That is muscle memory for sure.
