Loneliness Is Killing You is a five-part series on the health effects of loneliness and social isolation. As part of an Association of Health Care Journalists International Health Study Fellowship, KCUR reporter Alex Smith traveled to the United Kingdom to see how that nation is addressing the problem and what lessons the United States can learn from it. This reporting was made possible in part by a fellowship sponsored by the Association of Health Care Journalists and supported by The Commonwealth Fund.
