Building new relationships with people is never an easy task. That is why there is such a great demand for people to connect with one another. Dozens of studies have shown that people who have satisfying relationships with family, friends, and their community are happier, have fewer health problems, and live longer. One study by Harvard Medical School, which examined data from more than 309,000 people, found that lack of strong relationships increased the risk of premature death from all causes by 50% - an effect on mortality risk roughly comparable to smoking up to 15 cigarettes a day, and greater than obesity and physical inactivity.
