There was a funny statistical artifact I read once (well, for some value of 'funny') that home was a terrible place to have a heart attack, because people are willing to 'just lie down and see how I feel' rather than in a restaurant or movie theater where an ambulance will be called.

It would be interesting then for similar studies to add a dimension in addition to self-reported loneliness on self-reported time spent outside the home. While it's likely that sedentary elders are lonelier, it's not a 100% overlap (some elders live with close family and some lonely people are still very physically active/outside). You would expect lonely, active people to have lower death rates than lonely, sedentary people with similar pre-existing conditions under your hypothesis, and it would be a powerful thing to prove because it's a lot easier to make people go out than to make them make friends.

Then what about work from home? Does it increase mortality?

I bet any change in mortality due to increased isolation is offset by decreased deaths due to traffic acidents.
