hi loloquwowndueo, i was thinking the same thing, but then I thought why you would prefer reading a book while sitting instead of listening - is it about efficiency and that if you CAN read one should (you use the imperative) read? I also have this view, but when I was young and an avid reader I also enjoyed radio stories immensely as my imagination was also activated. As in the past we were an species with a predominantly oral cultural transmission, arguably more 'embodied', there could be something to say for attending a theatre version in preference of a book. On the other hand, reading often is faster, but it's indirect, you translate the symbols into your imagination yourself, on the upside you perhaps train your mind more. So both have their advantages, one is not necessarily better. I notice I am often looking through a lense of efficiency and then make choices where I loose a certain experience - sitting in the dark listening to someone telling a story instead of reading can be equally wonderful.
Reading is faster - a reason not to do it! There’s a reason that rituals across time and space have had readings from time immemorial- and not just because of the cost of printing.
Especially with a work like LotR it can be very tempting to skim parts; the audiobook will just continue on, which can help you encounter passages you’d normally have skipped over.
