Can you get absorbed in a movie or binge watch a TV show? If so, I suspect your attention ability is still intact. You just need to re-practice consciously directing it again. I still struggle with it too, but was able to "get lost" in a book again. It was key though to move my phone way out of the room, and was hard to get started.

As a fellow 34 year old, no. Most movies these days are way too long and boring. Most shows it's tough to watch even a full episode in one sitting. Let alone binge a season.
I think, for me, it's because there's just too many things on my mind. And a lot of stuff just feels like it isn't worth my time. Why am I sitting here watching a dumb thing that kinda bores me when I could be working on any of the multiple dozens of tasks on my plate?
The only thing that works is getting a little high. Because you do need to give your brain a rest.
For reading books, audio and going on a long run is great. I read dozens of books per year that way. It's great and far less boring than shows.
Dont' watch modern media. Dive into old films that stand the test of time. Anything by Godard, Kurosawa, Fellini, etc.
I have awful attention spans, but I find that if I challenge myself by watching stuff out my comfort zone, I'm able to pay attention to it so well. If I know it's a great work of art, I find myself paying attention to just about every single shot, the composition of the frame, etc. It's incredibly rewarding, and it definitely makes watching most modern content impossible now
(That being said, I absolutely loved Pig and The Green Knight from this year)
