I can empathize with the commenter you're replying to. I still read for pleasure and have to read constantly for work of course. On some days, I feel like I can't. It is like exercising the same muscle every day which will lead to injury in a short amount of time. Switching to audiobooks or just taking a break does resolve that.
From what I am seeing around me though, reading for pleasure or even to gain knowledge has decreased a lot. I noticed it in adults first and this is being reflected in their children.
