FWIW, I do not read very long content on my PC. The webserial worm, which is in my top 5 of best all time series, I’d not have read if there weren’t ebook versions of it that you could load on an eReader.
You say you haven’t talked to many people like me, can you just concentrate on novels reading them on a screen exhausting to your eyes? Or does reading for hours on normal screens not exhaust them for you?
