Feeling lonely doesn't just feel awful: it's also awful for your physical health (spoiler: it is strongly associated with mortality). About one in four older adults in the UK suffer from loneliness, so this is a real issue. Yet, not much is known about how that feeling of loneliness manifests.

Last year, investigators used a very large sample of individuals from the UK to explore how our genes can predispose us to loneliness and our extent of regular participation in common social activities. They discovered 15 gene loci associated with loneliness, and 6 to 18 loci for various social activities such as going to the gym, frequenting a social club, or participating in a religious group. They also found that the gene loci associated with loneliness also overlapped with neuroticism and symptoms of depression, suggesting that these genetic factors may be involved in more serious mental conditions.
