I consume a lot of audiobooks - but I can really only listen to them in certain contexts when I am doing something else that requires a certain level of concentration: driving, gardening, cooking, cleaning and most of all walking. If I try and listen to them without doing something else I just fall asleep and I can't listen to them when doing something that requires a lot of concentration either.
I now have a lot of unused Audible credits because of the recent lockdown here which is lifting on Friday!
