This is a very interesting study. I’ll cede that there may, as quoting from the study, health benefits in friendships such as prolonged lifespan. However, are there any studies that explicitly show that people who are friendless suffer from psychological problems, compromised mental health issues, psychotic behavior as many of the others posters on here were implying earlier? These are the type of studies I am looking for, and I cannot find any that have been conducted. </p>
<p>As a counter example: Red whine has health benefits according to some studies. Would this imply that drinkers are more healthier than non-drinkers?</p>
