A UK study has found that 68% of adults say they feel lonely either often, always or sometimes. For 18 to 34 year olds, the number is 83%. 38 percent said they have less interaction with people now, than they did five years ago. 27 percent only interact socially with others once a week or less. UK adults spend only 4 percent of their time – around one hour a day – engaging in social interaction. On average, women spend 15 minutes longer interacting socially each day than men.
