I can sympathize, being approximately that age myself. I find myself struggling with simple shell one-liners, going to the AI as a crutch, suddenly remembering “obviously, yes, this is the way” and then getting frustrated at myself thinking “30 years ago, I would have had this whole thing done by now.”
Is my angst misplaced? Maybe. Does it affect everyone my age? Of course not. Would my 20 something self have done any better? Probably not.

As I near 60, I’ve come to realize I simply don’t have the same mental sharpness or stamina I used to."
Decline in mind sharpness. Decline in stamina.
