Thank you so much for sharing that, Lee! I haven't read it yet but will, and may even write about the topic for the paper.
In my other job as a copywriter, among my other duties is writing brochures for patients about medical devices. Most of them are pretty big-deal devices for serious conditions; implanting them may involving brain surgery or heart surgery. So the brochures almost always suggest lining up a caregiver, having that person go to doctors appointments with you and help you while you're recovering. They also often include instructions for the caregiver on how to help the patient.
I often say, what if this person doesn't have a caregiver? What if s/he has no spouse, either no children or they live somewhere else, no really close friends they could impose upon to that degree? The person giving me the assignment, generally someone in their 30s, will kind of shrug, like, well, pretty much everyone has somebody. But I don't think that's true for many, many people.
