Loneliness is bad for health and wealth in the U.K.

In the U.K., four in 10 citizens identify as being lonely at least some of the time, and people who report being often lonely incur about £850 more in annual National Health Service costs than their non-lonely counterparts, according to a study published in the open-access journal PLOS One by Nia Morrish from the University of Exeter, U.K., and colleagues.
