So if the fact she lived alone and had no one else to notice she was getting loopy (losing O2) made the COVID more onerous, would that fit?
Never mind her obesity and other issues, though generally you’d think she was healthy and active.
My reply concerned your misuse of the word "extenuating." In actual fact, the factors (obesity, "other issues") you mention should not be viewed as extenuating circumstances - but rather as exacerbating circumstances!
