My grandmother is in a similar boat as your mom would be in: obese, in her 90s, effectively zero mobility, and constantly afraid of becoming ill from something. The nursing home she's in doesn't allow visitors, and no doubt her health has deteriorated more from that than whatever risk she has of getting sick.

Someone wrote that this is the greatest crime against humanity this side of genocide or war crimes, and I agree. It's criminal what these people are doing, and it's made even worse that they'll never face justice for their crimes.
