I honestly think it’s too broad of a question since each of those types of people will be doing vastly different things through their time at home. I might play with my dog more often when unemployed, while a homemaker is on their feet caring for a child, and a retired person is doing home maintenance. All of those are different activities on foot, but maybe not available to people in different situations.
I could note however, my grandma has a standing sewing machine that’s pretty cool. As for books, I’ve used a music stand in the garage before, though maybe a podium of sorts would be better in the house.
