Having read the link, your title is rather misleading.
I know two people both over 75, one in his 80s one in his 90s. In the event of either or both of them becoming very ill with this virus I imagine both, or either, would be admitted to hospital.
Like many old people they are both living alone and the one in his 80s is still working in his own business. The one in his 90s is a very fit man who is still having daily walks.
Surely the article is referring to frail people in care homes who have someone to nurse them.
No one is going to be left to die alone in their own homes because they are over 75. Well, not yet, anyway.
