Socio-Feedback

Get married. Attend church. Join the Elks or even a Jacuzzi club. Whatever, so long as you keep in touch. Such behavior may be the best prescription for long and healthy life, according to research by Epidemiologist Lisa Berkman of the University of California at Berkeley. Studying the lives of 7,000 people between the ages of 30 and 69 over a nine-year period, she found that extraverts are more likely to live longer than introverts, who tend to be overweight, smoke, shun exercise and drink too much. While outgoing types are inclined to stay in better physical shape, Berkman concluded that their gregariousness, for unknown reasons, has much to do with the fact that they are more resistant to heart and circulatory diseases, cancer and strokes and less inclined to suicide. Which brings to mind Spinoza's observation, "Man is a social animal." And Psychologist James J. Lynch's new book, The Broken Heart: The Medical Consequences of Loneliness.
