I'm not a programmer per se, but I've encountered this. Probably after age 35 I noticed I couldn't remember stuff I wanted to come back to as well as I had become used to years prior. I've adapted by taking extensive notes & using a "To Do List" app on Android in which I can remind myself of stuff for later. I have to say though, this year is the first time I've used an Android, having been a BlackBerry fan since 2006. I still have yet to find a "Tasks" app as good as the BlackBerry's "Tasks" app. Perhaps worth mentioning is that I've also noticed that coffee (& caffeine in general) no longer provides the desired 'pep' & alertness it used to. I switched to Yerba Mate last summer & it didn't live up to the hype that caught my interest. Was lurking on r/Nootropics for awhile before deciding that would be too expensive to try. Saw some success stories there, so I figured I'd mention it here. YMMV Best of luck!
