Compared to people living in spousal union, the divorced, widowed or never married were 42 percent more likely to develop cardiovascular disease and 16 percent more likely to have coronary heart disease, the study found.
The risk of dying was likewise elevated for the non-married, by 42 percent from coronary heart disease and by 55 percent from stroke.

Having someone around to take care of one’s health problems and keep track of one’s meds is probably a plus, as are two incomes or pensions instead of one.
More intangibly, not living alone is thought to be good for morale, and for neural stimulation. People living in couples, earlier research has shown, also have lower rates of dementia.
