Secrets to Long life
Good advice for a long life? As it turns out, no. In a groundbreaking study of personality as a predictor of longevity, University of California, Riverside scientists found just the opposite.
Friedman and Martin examined, refined and supplemented data gathered by the late Stanford University psychology expert Louis Terman and subsequent scientists on more than 1,500 bright children who were about 10 years old when they were first studied in 1921. "Probably our most amazing finding was that personality characteristics and social relations from childhood can predict one's risk of dying decades later," Friedman concluded.
The Longevity Project, as the study became known, followed the children through their lives, collecting information that included family histories and relationships, teacher and parent ratings of personality, hobbies, pet ownership, job success, education levels, military service and numerous other details.
"When we started, we were frustrated with the state of research about individual differences, stress, health and longevity," Friedman recalled. "It was clear that some people were more prone to disease, took longer to recover, or died sooner, while others of the same age were able to thrive. All sorts of explanations were being proposed - anxiety, lack of exercise, nerve-racking careers, risk-taking, lack of religion, unsociability, disintegrating social groups, pessimism, poor access to medical care, and Type A behavior patterns." But none were well-studied over the long term. That is, none followed people step-by-step throughout their lives.
When Friedman and Martin began their research in 1991, they planned to spend six months examining predictors of health and longevity among the Terman participants.
But the project continued over the next two decades - funded in part by the National Institute on Aging - and the team eventually involved more than 100 graduate and undergraduate students who tracked down death certificates, reviewed interviews, and analyzed tens of thousands of pages of information about the Terman participants through the years.
"We came to a new understanding about happiness and health," said Martin, now a psychology professor at La Sierra University in Riverside. "One of the findings that really astounds people, including us, is that the Longevity Project participants who were the most cheerful and had the best sense of humor as kids lived shorter lives, on average, than those who were less cheerful and joking. It was the most prudent and persistent individuals who stayed healthiest and lived the longest".
Part of the explanation lies in health behaviors - the cheerful, happy-go-lucky kids tended to take more risks with their health across the years, Friedman noted. While an optimistic approach can be helpful in a crisis, "we observed that as a general life-orientation, too much of a sense that 'everything will be just fine' can be dangerous because it can lead one to be careless about things that are important to health and long life. Prudence and persistence, however, led to a lot of important benefits for a number of years. It turns out that happiness is not a root cause of good health. Instead, happiness and health go together because they have common roots".
A number of of the UCR findings fly in the face of conventional wisdom. For example:
It's never too late to choose a healthier path, Friedman and Martin said. The first step is to throw away the lists and stop worrying about worrying.
"Some of the minutiae of what people think will help us lead long, healthy lives, such as worrying about the ratio of omega-6 to omega-3 fatty acids in the foods we eat, actually are red herrings, distracting us from the major pathways," Friedman said. "When we recognize the long-term healthy and unhealthy patterns in ourselves, we can begin to maximize the healthy patterns".
"Thinking of making changes as taking 'steps' is a great strategy," Martin advised. "You can't change major things about yourself overnight. But making small changes, and repeating those steps, can eventually create that path to longer life."

Good advice for a long life? As it turns out, no. In a groundbreaking study of personality as a predictor of longevity, University of California, Riverside scientists found just the opposite. "It's surprising just how often common assumptions - by both researchers and the media - are wrong," said Howard S. Friedman, distinguished professor of psychology who led the 20-year study.
