>I'm not noticing a "cognitive decline" per se
The funny thing is, maybe not noticing one can be the actual sign of it :)
Yes, precisely. Assessing your own cognitive skills is dubious. I’m pretty certain I’m less clever than I was when younger but if I find a problem tough now maybe 25 yo me would also have struggled?
That’s the most important thing. If we keep reading, maybe we can hold our own.
