"A study in Japan finds that social networks are an important predictor of mortality risk for middle-aged and elderly Japanese men and women. Lack of social participation for men, and being single and lack of meeting close relatives for women, were described as independent risk factors for mortality. Mortality rates showed a dose-response pattern: women with small social networks showing more than twice the death rate. Simply being single was associated with a higher risk of mortality, a prospective cohort study of 94,000 Japanese people found, and it concluded that merely being unmarried constitutes a potentially adverse health effect."
What will this mean to our evangelism efforts?
