People get lonely for lack of listening. Psychology and sociology researchers have begun warning of an epidemic of loneliness in the United States. Experts are calling it a public health crisis, as feeling isolated and disconnected increases the risk of premature death as much as obesity and alcoholism combined. The negative health impact is worse than smoking fourteen cigarettes per day. Indeed, epidemiological studies have found links between loneliness and heart disease, stroke, dementia, and poor immune function.
