Researchers focused on the subjective feelings of loneliness instead of socially isolated people. This particular finding grabbed my attention:
The average person experiences loneliness about 48 days a year, but having a lonely friend can add 17 days of loneliness annually. By comparison, every additional friend can decrease loneliness by about 5 percent, which translates to about two and a half fewer lonely days a year.
