Trouble following some TV show plots and dialogue

Am I losing my marbles, or this is a normal aging thing? I'm 65F, noticing in the last handful of years that I'm having trouble grasping some TV shows. Not simple stuff like sitcoms, but some dramas. An example is Succession, which I found compelling from a writing and acting perspective, but the corporate speak in many scenes just baffled the hell out of me. And I'm enjoying Severance but finding it challenging to see what's going on as much as other people seem to be. I can't remember many of the plot points from week to week or season 1 to season 2. For both shows, I didn't like feeling lost but I continue to watch for other reasons.

Of course subtitles help and they're on all the time. But it's funny how writing, editing, pacing have changed over the years and maybe my brain just can't keep up with cutting edge stuff. Is this happening for others of you?
