Helps beat cancer: University of Iowa researchers found that ovarian cancer patients with a strong sense of connection to others and satisfying relationships had more vigorous “natural killer” cell activity at the site of the tumor than those who didn’t have those social ties. (These desirable white blood cells kill cancerous cells as part of the body’s immune system.)
Leads to a longer life: The National Longitudinal Mortality Study, which has been tracking more than a million subjects since 1979, shows that married people live longer. Plus, they have fewer heart attacks and lower cancer rates, and even get pneumonia less frequently than singles. source: prevention.com: How Love Keeps You Healthy by Sandra Mahony
