I am in my late 30ies and few years ago I started to occasionally "lose" words. Never happened before... like the other day I couldn't remember the word raccoon. "Trash panda! Dumpster bandit! Badger? No. Beaver? No. Definitely not coyote. What was it?" the word just legit wasn't there when I needed it. My mind was wandering around it in the concept space, but couldn't find it until I googled. Affects both my native language and English.
It happens maybe once a week or even more rarely, but the scary part is what it symbolizes. The sack of shit that my mind uses for life support is starting to glitch! And I remember exactly how it feels for it to not be glitching. It's all downhill from here, but how fast?
I do exercise a lot and eat healthy, no kids, ok sleep, so it's also kinda depressing to read the comments - no obvious easy fixes to try!
