From one of the articles I cite below, "Marital stress is associated with lifestyle risk factors and nonadherence to medical regimens. Poor marital quality is also linked with more depression, hostility and anger, all risk factors for coronary heart disease. Thus, marital status and quality could influence metabolic risk factors and acute stress responses, which in turn predict cardio-vascular morbidity and mortality, according to the study."

"To the unmarried and the widows I say that it is good for them to remain single, as I am. But if they cannot exercise self-control, they should marry. For it is better to marry than to burn with passion" - The Apostle Paul, 1 Corinthians 7:8-9.
The point in the GP comment is with how many women refuse to marry below their income/professional status and socioeconomic level.
