Yeah, exactly. If you cook, do aerobics, walk your dog, commute, do chores, or even run errands, you potentially have time you can enrich with a good podcast.

For example, these days I have trouble reading books because it's so sedentary. I can only do it for 30min before I switch to a podcast or audiobook so I can run or cook or do pushups while I listen.

For me the efficiency is its main perk.
