Self-ratings of health have consistently been shown to be a strong predictor of future health outcomes, including mortality, morbidity, and chronic diseases. Objective assessments of exercise habits and the number of times visiting the doctor can also be indicators of future health, but self-ratings of health are generally more reliable and have a stronger association with health outcomes. A spouse's rating is not as reliable as an individual's self-rating of health.
