Actually, I used to love reading, but the last years I've felt exactly like I had no energy to read any more, and have switched to audiobooks and podcasts. I then checked my eyes, and it turns out I need glasses. So as you get older, check your eyes!
I have had glasses since I was 7... A year after my father brought home a 'portable computer' (luggable) [0] with a tiny monochrome screen. Not sure if that was related, but I guess it could be as the screen was very tiny (see pic below).
