What research shows about aging.

For more than 80 years, researchers have also been collecting data for The Longevity Project, which examines the lifestyles and behaviours of 1,500 people in San Francisco who were selected to participate in 1921Ñwhen most of them were 10 years old. Some of the results have turned conventional wisdom on its head, says lead investigator Howard Friedman, psychology professor at the University of California in Riverside, who analyzed the data and published the results with co-author Leslie R. Martin in the 2011 book The Longevity Project. For instance, we've long been told that married people live longer, healthier lives than singles. But Friedman says, "In our studies, women who got divorced or stayed single often thrived. Even women who were widowed often did exceptionally well." The key may be in social connections, which are vital to physical and mental health and which women tend to seek out and maintain; divorced men often lose these connections and are at high risk for premature mortality, Friedman says.
