People who are more isolated than they want to be from others find that they are less happy, their health declines earlier in midlife, their brain functioning declines sooner and they live shorter lives than people who are not lonely.
Inimesed, kellel on teistega vähem kontakte kui nad sooviksid, tunnevad end vähem õnnelikuna, nende tervis halveneb keskikka jõudes kiiremini, nende aju töövõime langeb kiiremini ja nende eluiga on lühem kui inimestel, kes end üksildasena ei tunne.
